How to Stop Excel Formula from Returning Fail for Blank Cells
Question details
The user needs a formula to ignore blank cells and return a blank output instead of interpreting them as zeroes and returning a 'Fail' result.

- Device & OS
- not provided
- Scenario
- Evaluating whether five specific cell values fall between 0.3 and 1.3 using a COUNTIFS formula.
- Observed behavior
- The formula evaluates empty cells as zeros, causing the COUNTIFS condition to fail and incorrectly outputting 'Fail' instead of leaving the cell blank.
Ensure you know whether the formula should return a blank if just the first cell is empty, if any of the cells are empty, or only if the entire range is completely empty. Also, verify that your blank cells do not contain hidden spaces.
Use ISBLANK to Check a Single Leading Cell
This is best when the entire row of data depends on the presence of a value in the primary reference cell (e.g., V138).
By wrapping your original formula in an IF and ISBLANK logical test, you can force Excel to check for data before running the COUNTIFS function.
Click on the cell where you want the Pass/Fail result to appear.
Type `=IF(ISBLANK(V138),"",IF(COUNTIFS(V138:Z138,">=0.3",V138:Z138,"<=1.3")=5,"Pass","Fail"))` into the formula bar.
Press Enter. If V138 is empty, the cell will remain blank. Otherwise, it will evaluate the range and return 'Pass' or 'Fail'.

Use COUNTA to Check if the Entire Range is Empty
Use this method if the calculation should only be skipped (and return a blank) when all five cells being evaluated are completely empty.
Use OR with ISBLANK to Check All Individual Cells
Apply this solution if the presence of even a single empty cell in your five-cell range should void the test and result in a blank.

Frequently Asked Questions
Why does Excel treat blank cells as zero in my formulas?
In many mathematical and logical operations, spreadsheet software defaults to interpreting a null or completely empty cell as a numerical zero to allow calculations to complete. Using functions like ISBLANK overrides this default behavior.
Why is ISBLANK returning FALSE when the cell looks empty?
ISBLANK strictly checks if a cell is entirely devoid of content. If the cell contains a hidden space, a hidden character, or a formula that outputs an empty string (""), ISBLANK returns FALSE. For formulas returning empty strings, checking equality like `=A1=""` is more effective.
Can I use IFERROR instead of ISBLANK for this problem?
No. IFERROR only triggers when a formula returns a standard error code (like #DIV/0! or #VALUE!). Because treating a blank as a zero and outputting 'Fail' is a logically valid calculation as far as the software is concerned, it does not trigger an IFERROR condition.
