If you are having this issue “Why is my VLOOKUP not working?, don’t worry; we are here to help you with a solution. In this guide, we’ll take you through the five most common reasons that VLOOKUP fails and the simple, common-sense fixes that you can use for each issue.

1. VLOOKUP #N/A Error: You are Looking For an Exact Match

The #N/A error in Excel’s VLOOKUP function often occurs when you’re looking for an exact match, but something prevents the function from finding it. If you encounter this error, this could be due to looking for an exact matching value, and VLOOKUP doesn’t find the exact matching value, it returns an #N/A error. However, if you use the approximate matching mode, the VLOOKUP function will look for the Exact matching value first, and if it does not find it, it will look for the nearest smallest value in the data. If you are looking for the exact matching value, you should type FALSE at the end of your formula, so Excel knows you’re looking for that one specific value.

Now, here’s something important: this part of the formula is optional, meaning you can skip it. But if you don’t write anything, Excel will automatically use TRUE instead. And when TRUE is used, Excel won’t look for an exact match, it will look for the closest match it can find. And then VLOOKUP will return the wrong value rather than the exact match you are looking for. For that to work correctly, your data must be sorted in ascending order (like A to Z or 1 to 100). If it isn’t sorted properly, Excel might give you the wrong answer.

In some cases, when this part is left out and the data isn’t sorted, the VLOOKUP formula can return a completely incorrect result, which can be very confusing if you don’t realize what’s going wrong.

Solution:

So, to manage this error and overcome the incorrect results returned by the VLOOKUP function, you must first use the correct spellings for the exact matching lookup values. Excel, for example, does not consider “Apple” and “apple” to be similar.

Second, you can use the TRIM function to remove extra spaces or clean your data.

=TRIM(A2)

Thirdly, you have to set the fourth argument of VLOOKUP to FALSE, and it will then return the exact matching value instead of giving a #N/A error or giving the wrong value in the results.

2. The Lookup Column Is Not the First Column or You Have Inserted a Column

The other most common reason for your VLOOKUP not working could be that your lookup value is not in the first column. We all know that the VLOOKUP function only works from right to left and cannot look up for a value from its left side or other columns than the first one. VLOOKUP searches down the first column of your given range. VLOOKUP will give you false results and will return errors as a result if you ever try to look up a value in other columns rather than the first column.

Also, the VLOOKUP method does not operate if you have first created an empty column, either by accident or on purpose. It will analyze the first data column and search for the value down until it finds what you are looking for.

Solution:

The possible solution to this error is that you should always look up a value in the first column and remove any empty columns.

The second method is to use INDEX-MATCH, which is more flexible and powerful. You can use this combination in the VLOOKUP function because it allows you to search for a value from any column.

=INDEX(C2:C10, MATCH("Apple", B2:B10, 0))

3. Your Data Table has increased

The other reason VLOOKUP cannot work is that you have added more rows to the data table in which you are looking for a certain value. But you haven’t adjusted the formula to add up the rows in the cell ranges. If this occurs, your VLOOKUP doesn’t work and will return errors. 

Solution:

The solution to this problem is simple: You just have to add the additional rows to the VLOOKUP formula as cell ranges. Make sure that the cell ranges cover the entire table in which you are searching for a value.

The second possible solution to this problem is to turn the lookup range into a table. You only need to select the data range and then go to the Insert Tab to turn it into a table. When you convert to a table and add additional rows of data, VLOOKUP will consider them to be part of the lookup range. VLOOKUP will then use the table as the lookup range rather than the specific cells.

You can see in the image that after changing the cell ranges from A2:C7 to A2:C10, the complete data table has been selected. 

4. VLOOKUP Not Matching Text: The Data Types Don’t Match

When VLOOKUP does not match text because the data types in the lookup value and the data table don’t match, the problem usually stems from differences in formatting (e.g., text vs. numbers) or trailing spaces. Here are steps to troubleshoot and resolve the issue:

1. Verify Data Types

Check if the lookup value and the table column are the same data type (text or number).

• In Excel, use the =TYPE(cell) function to check the data type of a cell:
  • Returns 1 for numbers.
  • Returns 2 for text.
• Ensure both the lookup value and the table column are the same type.

2. Convert Numbers Stored as Text

Convert Text to Numbers:

• Select the range with numbers stored as text.
• Use the “Text to Columns” tool in the Data tab:
  • Highlight the range.
  • Go to Data > Text to Columns > Finish.
• Or multiply by 1 (=A1*1) or add 0 (=A1+0) in a helper column and copy-paste as values.

Convert Numbers to Text:

• Use the TEXT(cell, "0") formula.
• Alternatively, use =TEXT(cell, "@").

3. Remove Extra Spaces

Use the TRIM function to clean up extra spaces in both the lookup value and the table column:

• In a helper column, enter =TRIM(A1) to remove leading, trailing, and extra spaces.
• Replace the original data with the trimmed data.

4. Ensure Consistent Formatting

Check for consistency in formats:

• Select both the lookup value and the table column.
• Format both as “General” or “Text” (Home tab > Number dropdown).

5. Handle Non-Printable Characters

Use the CLEAN function to remove hidden characters from the data:

• In a helper column, enter =CLEAN(A1).
• Replace the original data with the cleaned data.

6. Force Exact Matches

Ensure your VLOOKUP formula includes the exact match argument:

=VLOOKUP(lookup_value, table_array, col_index_num, FALSE)

FALSE forces Excel to look for an exact match.

7. Check for Hidden Characters

Sometimes, data may contain hidden characters (e.g., non-breaking spaces). Use the CODE function to identify these:

• =CODE(MID(A1, 1, 1)) checks the first character.
• Remove the offending characters using SUBSTITUTE:
  • =SUBSTITUTE(A1, CHAR(160), "") (to remove non-breaking spaces).

8. Manually Re-enter Values

If the above methods fail, re-entering the data manually in both the lookup value and table column can resolve the issue.

Example

Problem: Lookup value is “123” (text), but the data table has 123 (number).

1. Convert Lookup Value to a Number:
   

   =VALUE("123")

2. Convert Table Column to Text:
   

   =TEXT(A1, "0")

3. Use the adjusted data in your VLOOKUP.

Final Formula:

=VLOOKUP(VALUE(A1), table_array, 2, FALSE)

In the solution, you can convert these numbers to actual numbers by using the TEXT() and VALUE() functions. After that, your text-sorted numbers will be converted to real numbers, and you will be able to see results rather than errors.

5. The Range Isn’t Locked When Copying the Formula

Another major issue that causes VLOOKUP to not perform properly is moving the VLOOKUP formula between rows or columns. When you do that, your range might change unintentionally. In Excel, when you are copying a formula, it causes relative references to update based on the new location. If your table range changes, the lookup will not function properly.

In the image above, you can see that the formula produces the right results.

And when you drag and drop the same formula for the cell F3, Excel not only updates the lookup value from E2 to E3, but it also updates the lookup range, which causes the issue. 

Solution:  

A solution to this problem is to lock your lookup table (the table in which you are looking up information), also known as table_array. To lock your lookup table, you can use dollar signs $.

=VLOOKUP(E2, $A$2:$C$10, 2, FALSE)

Now you can see that the lookup range has not changed when dragging the formula down to cell F3. 

6. VLOOKUP #REF Error: The Column Index Number Is Incorrect

The third argument in VLOOKUP is the column index number, which is the number of the column in the table array from which to get a value. If you enter a column number that does not exist in your range, you will receive an error or an inaccurate result.

As you can see in the above image, the column-index-number is set to 4. And the D column is empty, so it returns an error. 

Solution:

To fix this error, simply check and correct your column index number, just like below:

7. VLOOKUP Not Working: Data Contains Duplicates and Non-Unique Values

Another common cause why your VLOOKUP isn’t working is that your data table contains non-unique and duplicate values, as shown in the image.

VLOOKUP returns only the first match that it finds. So, if your lookup column contains many entries with the same value, Excel will always return the value from the first one, even if there are others with different values.

Solution:

The first and simplest solution to this problem is that you can remove duplicates by clicking the Remove Duplicates option on the Data tab.

The second solution for you can be to use newer functions such as FILTER() (available in Excel 365) or complex formulas with INDEX to return multiple matched values.

8. Your Lookup Value is On the Left Side

VLOOKUP only works when the value you’re searching for is in the first (leftmost) column of your selected table range. If your lookup value is in a column to the right of the return column, VLOOKUP won’t work and will return an error. As you know that VLOOKUP can only look up from left to right; it can’t search to the left of the data table. So if you try to search for a value in Column C and return a result from Column A, VLOOKUP will fail.

Solution:

To avoid this error, you can move the lookup column to the left side of your dataset.

And the second option is that instead of using VLOOKUP, you can combine the INDEX and MATCH functions. This combination lets you look up in any direction. INDEX-MATCH allows you to find values independent of their position (left or right), making it more versatile than VLOOKUP.

The Third solution for this problem can be using the XLOOKUP function, which is more advanced. Using the XLOOKUP function, you can look up in any direction and will encounter fewer issues than with VLOOKUP.

Bonus Tips to Avoid VLOOKUP Errors

Sort Carefully: 

If you are using approximate match (by setting the fourth argument to TRUE), make sure the first column is sorted in ascending order. If you are using the exact match, make sure to set the fourth argument to false. Otherwise, it will return a #N/A error if it does not find the exact matching value in the data table. 

Use Named Ranges: 

Always make sure to use name ranges when working with the VLOOKUP function. And when you use named ranges, this will make your formulas cleaner and easier to understand.

Try XLOOKUP: 

If you’re using a newer version of Excel, the XLOOKUP function is a more modern, flexible alternative to VLOOKUP. In XLOOKUP, you will not encounter these problems that you might face using other lookup functions like VLOOKUP.

VLOOKUP Not Working: Conclusion

If you’ve ever felt stuck and thought that VLOOKUP is not finding the exact matching data or why you’re getting wrong results, you’re not alone. Whether it’s a VLOOKUP not matching text issue or even VLOOKUP returning the wrong value, the truth is, a small mistake in your formula or data structure can throw everything off. But now that you know what to watch out for and how to fix these common issues, you’ll find it much easier to troubleshoot whenever VLOOKUP is not working. Just remember to check your ranges, watch your column index, handle text and duplicates carefully, and don’t hesitate to try functions like INDEX-MATCH or XLOOKUP for more flexibility.

Excel is an essential tool for managing and analyzing data. Among its many time-saving features, Autofill stands out as a powerhouse for automating repetitive tasks. Whether you’re populating rows of dates, copying formulas, or creating sequential numbers, Autofill simplifies your workflow and minimizes errors.

But sometimes, it doesn’t always operate as expected. In this article we will discuss the reasons why Autofill doesn’t always work as well as it should.

What is Autofill in Excel 

If you’ve ever worked with Excel, you may notice a small square in the bottom-right corner of a cell. This little tool is known as the Autofill Handle. Autofill allows you to automatically fill fields with data that follows a pattern or to copy information or formulas from one cell to another. It saves a lot of time, especially when working with large datasets.

It can be used to continue a series, repeat a value, copy formulas along a column or across a row, or expand patterns such as days in a week, months, or custom lists. With Autofill, you can quickly populate hundreds or even thousands of cells, saving time and reducing manual errors.

How to Use Autofill in Excel

Let’s break it down into simple steps so that everyone can understand it and improve their data management while saving time. 

Using the Fill Handle

The Fill Handle is the small square at the bottom-right corner of a selected cell. It’s your gateway to Autofill magic. Let’s assume that you want to autofill numbers in an Excel sheet. To autofill, you can just follow these simple steps.

1. First, type the number like 1, 2, 3 or any other number such as 12 in column C1 and the second number sequence (13) in C2. 
2. Now select both cells C1 and C2. 
3. Move your mouse to the bottom-right corner of cell C2. 
4. You’ll see a small square. Click and drag the square down to fill more cells.

Now you can see that the other cells are automatically filled by the next number sequences as above.

Autofilling Sequence Numbers 

If you want to autofill a single value in multiple cells, follow these steps:  

1. Type the number you want to autofill in multiple columns, such as 14 in C1. 
2. Look for the plus sign on the bottom right corner of C1.
3. Click on it and drag it down to other cells.

You can see from the image that the number 14 has been automatically filled in the other cells.

Autofilling Multiple Kinds of Data 

As you can see in the image above, it can easily autofill any type of text sequence, arithmetic progression sequence, and even alternate sequences in Excel.

The process is the same as we explained in the previous examples. Simply select the first two to three cells or more containing your text, numbers, arithmetic, or any other sequences.

And then simply drag down the + icon to the desired cells where you want to fill the sequences.

Autofill in Excel for Dates, Months, and Times 

Excel recognizes patterns in dates and times, making it easy to create schedules or timelines.

Just type dates, months, and times in Excel, just like other text and numeric values and drag the Fill Handle to extend the data. Your data will be autofilled in further cells. 

Advanced Options:

• Right-click while dragging the Fill Handle to choose options like Fill Days, Fill Weekdays, or Fill Months.

Autofilling Multiple Columns and Rows

If you have data in numerous cells and columns and want to autofill all of them, the autofill function can help you do that. Simply select all of the rows and columns, then drag the fill handle, and your data will be automatically filled in the other cells, as shown in the image below.

Using Autofill While Inserting Empty Cells

You can also use the autofill feature to create gaps in your data sequences. The process is also the same as the other approaches shown in the figure below.

Autofilling Formulas

Autofill doesn’t just work with numbers and text, but it’s equally as powerful for formulas.

1. In cell C1, type =A1+B1.
2. Hit Enter.
3. Click C1 again.
4. Drag the Autofill handle down.

Excel will update the formula automatically in each row (e.g., =A2+B2, =A3+B3). You don’t have to re-type the formula over and over.

Using Autofill With Custom Lists

If you want to reuse the same list of products, you can create custom lists in Excel. A custom list only includes text values and text with numerical values. To do so, save the specified products and text value list as a custom list in Excel and then use the autofill feature to populate that custom list in further cells. 

You can follow these simple steps to create and save a custom list in Excel.

1. First, make a list of all of the products you want to add to your custom list.
2. Go to File > Options > Advanced.
3. Go to the ‘General’ section and select the box of ‘Edit Custom Lists’.
   

   

4. Add your list (e.g., “Apple, Banana, Mango, Orange, Kiwi, Cherry”) and click OK.
   

   

5. You can also choose the option to import a list from cells.
   

   

Finally, after creating the custom list, you can add it to any cell by entering the first product and dragging the autofill handle to the desired cell. Excel will then identify the custom list and populate it in the remaining chosen cells. 

Flash Fill

Has it ever happened to you that after entering the first character or values in a cell, Excel provides the remaining entries or that specific value? This can sometimes happen using Excel’s Flash Fill feature.

When you enter data into Excel and then follow a pattern, Excel recognizes it. When you add the first characters of a value, Flash Fill suggests the other characters based on the pattern you followed.

As you can see in the image above, Excel displays a list of names. When you press the Enter button, all of the cells will be automatically filled with the following data patterns.

The Excel Flash Fill function allows you to easily format any type of data, including dates and times.

Simply enter the first character of any data, and FlashFill will manage the rest. 

Why Doesn’t Excel Autofill Work Sometimes?

If you are using Excel and notice that your Excel autofill feature is not working, there could be a few reasons for this. So let’s investigate and try to fix them.

Things to Try First

There may be minor system or software issues that can create problems. To correct them, try these methods first. 

• Restart Excel and if that does not work restart your computer.
• Check the Excel version and update it.
• Check if you have installed Excel using an illegal or cracked method. This can also cause Excel functions to not work properly. 
• Check if there’s any filter on the data you have entered and then clear it. 
• Replace the range of cells.
• Check if the autofill option is disabled in Excel and then enable it. To check if Autofill is enabled in Excel, go to File > Options > Advanced, then look under Editing options and make sure “Enable fill handle and cell drag-and-drop” is checked. If it’s not, tick the box and click OK to enable it.

1. Missing a Pattern

Autofill only works by recognizing a pattern. If you enter data into an Excel sheet without following the pattern or missing a value, Excel will not function properly. For Example:

• If you type 1 in cell A1 and nothing in A2, Excel won’t know if you want to continue 1, 2, 3 or just copy 1 repeatedly.

Solution:

To resolve this issue, always give Excel at least two cells to work with. For example, if you want to repeat 2, 4, 6, 8, etc., you can enter 2 and 4 in the first two cells and then use the autofill option.

Using this method, autofill will recognize and follow the pattern.

2. Formula Doesn’t Adjust Properly

If you work with formulas in Excel, you may find that autofill does not always work. Working with formulas does not change the way you expected. This often happens when you use absolute references, such as $A$1. 

Example:

• In D1, if your formula is =A1*$B$1, and you Autofill down, A1 will become A2, A3… but $B$1 will stay the same.

Solution:

When working with formulas, you need to use $ signs carefully and correctly; otherwise, you will produces incorrect results.

To achieve the correct results, simply use =A1*B1

In some cases, the $ sign produces correct results, and sometimes it produces incorrect results; therefore, you need to know how relative and absolute cell references work.

3. Formatting Doesn’t Match

Wrong formatting can also give you unexpected outcomes. If you format your starting data, the remaining data will likewise be formatted, which you don’t want. For Example:

• If A1 is bold and red, dragging the handle will make all filled cells bold and red too.

Solution:

In this case, you can use the Autofill Options button to choose “Fill Without Formatting,” which appears after you drag.

4. Excel Just Copies, No Pattern

Sometimes, after writing data, you simply drag it. In this case, Excel will just copy the data you’ve typed into the cells. For example, you typed 1, 3, 5 and dragged… but Excel keeps copying 1, 3, 5 instead of continuing 7, 9, 11.

Solution: 

If this ever happens to you, then you can use the Fill Series option after dragging to tell Excel to extend the pattern.

5. Manual Calculation Mode

There is a manual calculation mode in Excel; if this is enabled, the formulas will not be properly updated, resulting in inconsistent results.

Solution:

To fix this issue, you can go to the Formulas tab > Calculation Options > and Select Automatic.

How To Turn On and Off the Autofill Feature?

The autofill handle is enabled by default, which appears when you enter data into cell ranges. If you want to turn off the autofill feature that appears every time you select a cell, follow these steps:

1. Click on File (or the Office button if you’re using Excel 2007).
2. Choose Options, then go to the Advanced section.
3. Under the Editing options group, uncheck the box labeled Enable fill handle and cell drag-and-drop.
   

Once unchecked, Excel will no longer allow you to use the fill handle for dragging or AutoFill.

Show or Hide the Autofill Options Button

To hide the autofill handle in Excel, simply follow these steps:

1. Go to File (or the Office button), then select Options, and proceed to the Advanced tab.
2. Navigate to the section labeled Cut, Copy, and Paste.
3. To hide the AutoFill Options button, uncheck the “Show Paste Options” button when content is pasted.

Once disabled, the Auto Fill Options icon will no longer pop up after you drag the fill handle.

Wrap Up

Excel Autofill is a time-saving feature that helps you quickly populate data, formulas, and patterns. Once you know how to utilize Autofill in Excel using the Excel fill handle, repetitive tasks become much easier.

However, if Excel Autofill is not working, it’s often due to a missing pattern, wrong formula references, or disabled settings. Use the tips in this guide to troubleshoot issues and make the most of this powerful tool.
