Fix SUMIF or SUMIFS Returning Blank or Incorrect Results in Excel
Question details
The user needs to resolve an issue where SUMIF or SUMIFS formulas output blank or incorrect values, even though other formulas like SUM and VLOOKUP function normally.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Calculating conditional sums using SUMIF or SUMIFS across linked sheets or within Excel for the web.
- Observed behavior
- The SUMIF or SUMIFS formula includes blank cells or returns unexpected incorrect results, which often resolves temporarily when the file is copied to a new workbook.
Check if your worksheet contains any hidden columns or linked external workbooks that might be affecting the calculation range of your formulas.
Save a Copy of the Workbook
Excel for the web occasionally experiences temporary calculation glitches. Creating a fresh copy of the file can reset the calculation engine and resolve the blank results.
When working in Excel for the web, temporary synchronization issues can cause advanced formulas like SUMIF and SUMIFS to fail, even when simpler formulas like SUM and VLOOKUP work perfectly. Saving a copy forces the web application to rebuild the file and re-evaluate all formulas.
Access your problematic workbook in Excel for the web or the desktop application.
Click on the 'File' tab in the top-left corner, select 'Save As', and then click 'Save a Copy'.
Open the newly created workbook and check your SUMIF or SUMIFS formulas to see if the correct numbers are now displayed without blank errors.

Share a Sanitized Test File for Troubleshooting
If the issue is workbook-specific or related to complex linked sheets, isolating the problem in a sanitized test file helps identify the root cause without compromising sensitive data.

Frequently Asked Questions
Why does my SUMIFS formula work in the desktop app but not in Excel for the web?
Excel for the web occasionally experiences synchronization or memory issues with complex formulas or linked workbooks. Saving a copy of the file often resets the calculation engine and fixes the output.
Can hidden columns affect my SUMIF results?
Yes. If your formula references a broad range, it evaluates hidden cells within that range. If those hidden cells contain unexpected data or blanks, your final sum will be incorrect.
Why does VLOOKUP work while SUMIFS returns an error in the same sheet?
VLOOKUP typically looks for a single exact match, while SUMIFS aggregates multiple cells based on criteria. If the criteria range contains mismatched data types, text formatted as numbers, or unlinked external references, SUMIFS will fail to aggregate correctly even if VLOOKUP succeeds.
