Formula troubleshooting

Fix Excel Formula Errors

Diagnose and fix the most common Excel formula errors, including #N/A, #VALUE!, #REF!, #DIV/0!, #NAME?, #NUM!, and #SPILL!.

Fast error diagnosis

#N/A usually means a lookup did not find a match.
#VALUE! usually means a formula received the wrong data type.
#REF! usually means a referenced cell or range was deleted or moved.
#SPILL! usually means a dynamic array formula cannot expand because cells are blocked.

Troubleshooting workflow

Check the first error in the chain before fixing downstream formulas.
Use Evaluate Formula to step through each argument.
Use IFERROR for user-friendly output only after the formula logic is correct.
