Google Sheets structural check
Google Sheets Formula Checker
Check balanced parentheses and quotes, separator consistency, literal broken references and recognizable function tokens. This local helper does not execute your sheet or inspect cell values.

Excel and Google Sheets are similar, not identical
Many common functions share names and syntax, but each product also has functions and behaviors the other does not. An “unknown function” warning can therefore mean a valid Google Sheets-specific function rather than a typo. Always confirm the final formula in the spreadsheet product where it will run.
What this checker can and cannot see
CellLingo can inspect text structure, but it cannot know whether a range exists, whether a named range is defined, whether an array has room to expand or whether the data types in your sheet match the formula's assumptions.
