VLOOKUP in Excel is one of those powerful functions that can dramatically improve your data analysis and management capabilities. However, when it comes to using VLOOKUP, many users encounter the common issue of returning blank cells instead of a zero when there’s no match found. This can lead to misunderstandings and misinterpretations of your data. Luckily, there are several tricks to make VLOOKUP return a zero instead of a blank. 🎉
Let’s delve into these 7 tricks to effectively utilize VLOOKUP with zero instead of blank cells in Excel.
1. Basic Syntax of VLOOKUP
Before jumping into the tricks, let’s clarify the basic syntax of VLOOKUP for those who might be unfamiliar:
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
- lookup_value: The value you want to search for.
- table_array: The table containing the data.
- col_index_num: The column number in the table from which to return the value.
- range_lookup: Optional. TRUE for approximate match, or FALSE for an exact match.
Example
Consider this example where we are looking for the price of "Apples":
Product | Price |
---|---|
Apples | 1.00 |
Bananas | 0.50 |
Grapes |
Using =VLOOKUP("Grapes", A2:B4, 2, FALSE)
will return a blank cell because there’s no price listed for grapes.
2. Using IFERROR to Handle Blanks
One of the easiest ways to ensure that you get a zero instead of a blank is by wrapping your VLOOKUP function with an IFERROR function. This function will catch any errors returned by VLOOKUP and replace them with a specified value, in this case, zero.
Formula:
=IFERROR(VLOOKUP("Grapes", A2:B4, 2, FALSE), 0)
Result:
This will return 0 instead of a blank when no match is found.
3. Combining VLOOKUP with IF
If you want more control over what gets returned based on different criteria, combining VLOOKUP with the IF function is a useful trick. This way, you can specify that if a blank is found, return zero.
Formula:
=IF(VLOOKUP("Grapes", A2:B4, 2, FALSE) = "", 0, VLOOKUP("Grapes", A2:B4, 2, FALSE))
Result:
This will check if the result of the VLOOKUP is blank and return zero if that’s the case.
4. Using ISNA for More Specific Error Handling
Sometimes, you may only want to replace specific errors with zero. In such cases, you can use the ISNA function with VLOOKUP. This method specifically looks for a #N/A error, which occurs when no match is found.
Formula:
=IF(ISNA(VLOOKUP("Grapes", A2:B4, 2, FALSE)), 0, VLOOKUP("Grapes", A2:B4, 2, FALSE))
Result:
This formula will return 0 for non-matching cases without changing other potential errors.
5. Using an Array Formula
For advanced users, utilizing array formulas can also solve the problem. This method requires using CTRL + SHIFT + ENTER instead of just ENTER after typing your formula.
Formula:
=IFERROR(INDEX(B2:B4, MATCH("Grapes", A2:A4, 0)), 0)
Result:
This will search for "Grapes" in the specified range and return 0 if nothing is found.
6. VBA Solution for a Custom Function
If you are comfortable using VBA, creating a custom function might suit your needs. This is a more advanced technique, but it provides maximum flexibility.
Example VBA Code:
Function VLookupWithZero(lookup_value As Variant, table_array As Range, col_index_num As Integer) As Variant
Dim result As Variant
On Error Resume Next
result = Application.WorksheetFunction.VLookup(lookup_value, table_array, col_index_num, False)
If IsError(result) Then
VLookupWithZero = 0
Else
VLookupWithZero = result
End If
End Function
Usage:
You would use it similarly to the built-in VLOOKUP:
=VLookupWithZero("Grapes", A2:B4, 2)
Result:
This custom function will return 0 for non-matches.
7. Creating a Helper Column
If you'd rather avoid complex formulas, creating a helper column in your dataset can also be effective. Add a column that converts blanks to zeros before using VLOOKUP.
Step-by-Step:
- Insert a new column next to your data.
- In the first cell of the new column, use:
=IF(B2="", 0, B2)
- Drag the formula down through the column.
- Use VLOOKUP on the new column.
Example Data
Product | Price | Adjusted Price |
---|---|---|
Apples | 1.00 | 1.00 |
Bananas | 0.50 | 0.50 |
Grapes | 0 |
Result:
Using VLOOKUP on this adjusted column will ensure that you retrieve 0 instead of a blank.
Troubleshooting Common Issues
Common Mistakes to Avoid
- Mismatched Data Types: Ensure that the lookup_value and the corresponding values in the table_array are of the same data type (e.g., both are text or both are numbers).
- Incorrect Table Range: Make sure your table_array range includes the lookup column and the column from which you're returning the value.
- Forgetting to Use Absolute References: When copying formulas, remember to use
$
to lock in cell references if required. - Incorrect Column Index: The col_index_num must be valid based on the number of columns in your table_array. If it exceeds the number of columns, you will get an error.
