Inspect formulas down a selected column, flag rows whose relative formula pattern differs from the dominant pattern, and export a report. Everything runs locally in your browser.
Formula patterns are compared structurally. Constants, blanks, and formulas that differ from the dominant relative pattern are clearly identified in the report.
The original file is never overwritten, and no file contents are uploaded by this page.

It checks file size and limits the on-page preview. Very large or complex workbooks may still exceed the browser’s available memory.
Browser spreadsheet libraries cannot preserve every advanced Excel object. Open the output and verify important values, formats, and business rules before relying on it.
