What is the Excel Formula Extractor?
Upload an Excel workbook (.xlsx, .xls, .xlsm or .xltx/.xltm) and this tool scans every sheet for formulas, then lists them out with quick stats: total formulas found, files processed, sheets covered, how many are 'complex' and how many distinct formula types appear.
Results land in a filterable, searchable table — search by formula text, filter by sheet or by complexity — so you can audit a large spreadsheet's logic without manually clicking through hundreds of cells. A reference tab and a history tab round out the workflow for repeat use.
