What is num error in Google Sheets?
Num Error is part of how Google Sheets surfaces formula problems, warnings, or diagnostics. Catching the message early keeps bad values from flowing into dashboards and reports.
When to use it
Use error messages as a checklist when a formula returns an unexpected result or blocks a dependent report.
When to skip it
Do not treat every warning as fatal; some loading or circular notices are expected during imports or iterative models.

Formula errors in Google Sheets
Formula errors are typed messages in cells when something prevents a valid result. Each code points to a different failure mode: bad reference, missing lookup, type mismatch, divide by zero, unknown name, or blocked array spill. Learning the vocabulary speeds debugging and keeps dashboards trustworthy for decision makers.
Read guide →#REF! error
#REF! means a formula references a cell or range that no longer exists. Common causes include deleted rows or columns, removed sheets, broken IMPORTRANGE, or cut-paste that orphaned an address. The error spreads to every dependent formula until you repair the link.
Read guide →#VALUE! error
#VALUE! means Google Sheets cannot interpret an argument as the type the function expects. Common causes include text in a math formula, invalid dates, wrong delimiter locale, or passing a range where a scalar is required.
Read guide →#NAME? error
#NAME? means Google Sheets does not recognize a name in your formula. That can be a misspelled function, a named range that does not exist, text used without quotes, or a function name from the wrong language locale.
