How to use IFERROR in Google Sheets
Catch errors
How IFERROR works
IFERROR shows a fallback value when a formula would otherwise show an error like #N/A.
IFERROR(formula, fallback)
Example on this data
=IFERROR(F2/0,"Can't divide")→Can't divide
Dividing by zero is an error, so the fallback shows.
What you’ll do
You’ll look up an order that doesn’t exist and show a friendly message instead of an error. Catching errors keeps a sheet readable when data is missing.
Try it
Type =IFERROR(F2/0,"Can't divide") into K2 and press Enter. Watch what the sheet does.
The result will appear in K2.
