6 Reasons Why Your VLOOKUP is Not Working

The VLOOKUP function is the most popular lookup and reference function in Excel. It is also one of the trickiest and the dreaded #N/A error message can be a common sight.

This article will look at the 6 most common reasons why your VLOOKUP is not working.

You Need an Exact Match

The last argument of the VLOOKUP function, known as range_lookup, asks if you would like an approximate or an exact match.

In most cases people are looking for a particular product, order, employee or customer and therefore require an exact match. When looking for a unique value, FALSE should be entered for the range_lookup argument.

This argument is optional, but if left empty, the TRUE value is used. The TRUE value relies on your data being sorted in ascending order to work.

The image below shows a VLOOKUP with the range_lookup argument omitted, and the incorrect value being returned.

Solution

If looking for a unique value, enter FALSE for the last argument. The VLOOKUP above should be entered as =VLOOKUP(H3,B3:F11,2,FALSE).

Lock the Table Reference

Maybe you are looking to use multiple VLOOKUPs to return different information about a record. If you are planning to copy your VLOOKUP to multiple cells, you will need to lock your table.

The image below shows a VLOOKUP entered incorrectly. The wrong cell ranges are being referenced for the lookup_value and table array.
VLOOKUP entered incorrectly

Solution

The table that the VLOOKUP function uses to look for and return information from is known as the table_array. This will need to be referenced absolutely to copy your VLOOKUP.

Click on the references within the formula and press the F4 key on the keyboard to change the reference from relative to absolute. The formula should be entered as =VLOOKUP($H$3,$B$3:$F$11,4,FALSE).

In this example both the lookup_value and table_array references were made absolute. Typically it may be just the table_array that needs locking.

A Column Has Been Inserted

The column index number, or col_index_num, is used by the VLOOKUP function to enter what information to return about a record.

Because this is entered as an index number, it is not very durable. If a new column is inserted into the table, it could stop your VLOOKUP from working. The image below shows such a scenario.
VLOOKUP could stop working if you inserted new column in the lookup table

The quantity was in column 3, but after a new column was inserted it became column 4. However the VLOOKUP has not automatically updated.

Solution 1

One solution might be to protect the worksheet so that users cannot insert columns. If users will need to be able to do this, then it is not a viable solution.

Solution 2

Another option would be to insert the MATCH function into the col_index_num argument of VLOOKUP.

The MATCH function can be used to look for and return the required column number. This makes the col_index_num dynamic so inserted columns will no longer affect the VLOOKUP.

The formula below could be entered in this example to prevent the problem demonstrated above.
Use the MATCH function to return dynamic col_index_num

The Table has got Bigger

As more rows are added to the table, the VLOOKUP may need to be updated to ensure that these extra rows are included. The image below shows a VLOOKUP that does not check the entire table for the item of fruit.
VLOOKUP does not check newly added rows

Solution

Consider formatting the range as a table (Excel 2007+), or as a dynamic range name. These techniques will ensure that your VLOOKUP function will always be checking the entire table.

To format the range as a table, select the range of cells you want to use for the table_array and click Home > Format as Table and select a style from the gallery. Click the Design tab under Table Tools and change the table name in the box provided.

The VLOOKUP below shows a table named FruitList being used.

VLOOKUP Cannot Look to its Left

A limitation of the VLOOKUP function is that it cannot look to its left. It will look down the leftmost column of a table and return information from the right.

Solution

The solution to this involves not using VLOOKUP at all. Using a combination of the INDEX and MATCH functions of Excel is a common alternative to VLOOKUP. It is far more versatile.

The example below shows it being used to return information to the left of the column you are looking in.

Your Table Contains Duplicates

The VLOOKUP function can only return one record. It will return the first record that matches the value you looked for.

If your table contains duplicates then VLOOKUP will not be up to the task.

Solution 1

Should your list have duplicates? If not consider removing them. A quick way to do this is to select the table and click the Removes Duplicates button on the Data tab.

Check out the AbleBits Duplicate Remover for a more complete tool for handling duplicates in your Excel tables.

Solution 2

Ok, so your list should have duplicates. In this case a VLOOKUP is not what you need. A PivotTable would be perfect to select a value and list the results instead.

The table below is a list of orders. Let's say you want to return all the orders for a particular fruit.

  3. Alan,Thank you very much!!!!!

  4. Another issue can be "unknown characters" instead of spaces being used. I was looking at a file with 2 sets of data that looked the same, but they were extracted by different means from a database, and on one set of data, spaces were not spaces but some other character. Found it by checking if 2 items that look identical were actually identical (they weren't, according to Excel), and the only possible characters that could be different were those I couldn't see, i.e. spaces.

    • Yes sometimes data needs to be cleansed after importing from a database before formulas such as VLOOKUP can be run.

      Text functions such as SUBSTITUTE and TRIM are great for this sort of tasks. The Find & Replace and Power Query tools are also brilliant for cleansing data.

  5. i want to use vlookup function my data have duplicate value but i don't want to remove it ,so i want use vlookup function but it gave me the first value of duplicate value i want to find the second value that belong to duplicate please help me

    • Hi Farid,

      Check out this video - https://youtu.be/QAZ3L6xbNJc

      It shows how to use VLOOKUP to return the last match if there are duplicates. You can adapt this easily for the 2nd match though.

  6. Hi Alan
    I'm doing a VLOOKUP which I do every month to put dates next to asset ID numbers. My LOOKUP results are exactly the same for every ID number when i copy down my formula. So the results for the first row are correct but the rest are wrong as they're the same as the first.

    • Hi Mel,

      It sounds like your lookup_value is absolute so is not changing when you copy the formula.

      You might need to remove the dollar signs from the first part of your VLOOKUP.

  7. While selecting rows and col in vlookup formula (the area where to search) the row col reference (eg. 8RX4C) is not displaying, It is getting difficult to count manually for larger tables.

    Please help me on this issue

    Thanks in advance

  8. Hello, Please help me understand why my vlookup formula stops working after 10 matches. My formula is very simple: =VLOOKUP(A7,'compiled responses'!B7:C804,1) my data is very simple: column "a" has numbers, column "b" has numbers

    col A col B
    404523 404523
    447135 447135
    447350 447135 this is where the formula stops working as it returns the incorrect value and then the values become N/A.

    I have checked the data is has no blanks, both columns are general input.

    I look forward to your assistance.

    Kindly,
    DH

    • I think your VLOOKUP by the sound of it is comparing columns A and B. And in this case it is stopping at that point because it is not a match i.e. 447350 is not equal to 447135.

  9. number could also be stored as text

    • Very true. The formatting of the values stored and the one searched for must be consistent.

      • Hi. Thanks for your reply. Unfortunately, it's still not working, even with all values consistent. Totally baffled!

  10. Hi - VLOOKUP is working fine for me apart from only returning the first letter, i.e returning only 'J' instead of John. Any ideas?

    • Not a clue. VLOOKUP will return all of the content from the cell, so as long as the full name is in there it will work.

  11. HI

    I want to use VLOOKUP with two diffrent spreadsheet which containt no match value on both, in that case is it possible to apply VLOOKUP in this manner??

    • It is possible to apply a VLOOKUP to two different spreadsheets. Ensure both workbooks are open when you write the VLOOKUP.

      Not sure what you mean by the contain no match on both, but VLOOKUP can help check for matches so sounds like it would work.

  12. Hi Alan...

    Do you have any idea why my VLOOKUP stopped refreshing automatically for ALL my spreadsheets. In your example, when I change I3, I actually have to click into the formula in J3 and hit enter for it to pull the refreshed value.

    • Hi Carlo,

      I think the cells containing the VLOOKUP's are formatted as text. I would select the cells and check the formatting on the Home tab.

      It may also be that you have manual calculation switched on. Click the Formulas tab and then Calculation Options.

      Alan

  13. Why VLOOKUP with "TRUE" condition is not working on dates?

    • It should work with dates no problem. Ensure the table is sorted in earliest to latest by the date.

  14. Thank you, the 'VLOOKUP cannot look to its left' was my pain was my issue. Totally unintuitive

  15. VLOOKUP Cannot Look to its Left was my issue.. thanks!

  16. Thank you Alan, you helped me with The Table has got Bigger.

  17. Thank you! My error wasn't any of these, but it was good to be encouraged to look through everything piece by piece. Turns out I had the initial column and the lookup_value formatted differently--one was Number and the other wasn't (somehow...) So, another goofy mistake, but maybe it will help someone.

  18. Why does my vlookup give the same answer?

  19. Hi,

    My table has duplicates in lookup cell, but the value against it is unique, what should I do if I want all the values populated?
    e.g
    Column A Column B
    Banana USA
    Watermelon Brazil
    Banana Columbia

    Now if I want both USA and Columbia in how should I get it, as vlookup only gives USA?

    • @Gautam Lapsiya Yes the VLOOKUP will only return the first answer.

      An option is to use a PivotTable like in the last example.

      Alan

      • Thanks Alan

  20. Watched the YouTube video and it was brilliant instruction!

    Saved me loads of time and frustration.

    Thanks so much.
