Step by step
- 1To check if A2 is blank, use =IF(ISBLANK(A2),"Empty","Has Value"). ISBLANK returns TRUE only for truly empty cells.
- 2Alternatively, use the empty string comparison: =IF(A2="","Empty","Has Value"). This also catches cells that contain a zero-length string.
- 3Combine with other logic to skip calculations: =IF(ISBLANK(A2),"",A2*B2) returns blank instead of an error when A2 is empty.
Tips
- ISBLANK is stricter than A2="". ISBLANK returns FALSE for cells with a zero-length string (""), while A2="" returns TRUE for them. Choose based on your data.

Frequently asked
What is the difference between ISBLANK and checking A2=""?
ISBLANK is TRUE only for a cell with no content whatsoever. A2="" is also TRUE for cells that contain an empty string formula result.
How do I count blank cells in a range?
Use COUNTBLANK(range) to count cells that are empty or contain empty strings, or SUMPRODUCT(--(range="")) for more control.
