Error fixes
Spreadsheet errors are messages, not mysteries. Each guide explains what the error means, the usual causes, and the proper fix — not just an IFERROR to sweep it under the rug.
Fix the #N/A Error
#N/A means your lookup found no match. Here's why it happens — usually invisible spaces or missing values — and how to fix or handle it.
=IFERROR(VLOOKUP(A2,Sheet2!A:B,2,FALSE),"Not found")Fix the #VALUE! Error
#VALUE! means a formula got the wrong type of data — usually text where a number should be. Here's how to find the culprit cell and fix it.
=ISNUMBER(B2)Fix the #REF! Error
#REF! means a formula points at cells that no longer exist — usually after deleting rows or columns. Here's how to repair and prevent it.
=INDEX(Data!C:C,MATCH(A2,Data!A:A,0))Fix the #DIV/0! Error
#DIV/0! means you divided by zero or by an empty cell. Guard the division with IF so averages and rates stay clean.
=IF(B2=0,"",A2/B2)Fix the #NAME? Error
#NAME? means the spreadsheet doesn't recognize something you typed — a misspelled function, text without quotes, or an undefined name.
=VLOOKUP(A2,Sheet2!A:B,2,FALSE)Fix the #SPILL! Error
#SPILL! means a dynamic array formula needs room to expand but something is blocking it. Clear the cells in its way and it heals itself.
=UNIQUE(A2:A20)Fix the #NUM! Error
#NUM! means a calculation produced an impossible number — a negative square root, a result too large, or date math that runs backwards.
=IFERROR(SQRT(A2),"Check input")Fix a Circular Reference
A circular reference means a formula depends on its own cell, directly or through a chain. Here's how to find the loop and break it.
=SUM(A2:A10)Fix the Formula Parse Error in Google Sheets
Google Sheets' formula parse error means the formula's punctuation is broken — wrong separators, smart quotes, or a missing parenthesis.
=IF(A2>10,"High","Low")VLOOKUP Returns the Wrong Value
No error, just wrong data — VLOOKUP quietly returns the wrong value when FALSE is missing, the column number shifts, or keys are duplicated.
=VLOOKUP(A2,Sheet2!$A:$C,3,FALSE)
