Hey everyone! 👋 ExcelErrorFinder is a free tool that scans your Excel spreadsheets and finds errors — broken formulas, hidden sheets, wrong numbers, broken links, and more. It then explains each issue in plain English and tells you how to fix it. What problem it solves: We've all sent a spreadsheet to a client or boss, only to find out later it had a #REF! error, a hidden row with old data, or a formula that didn't match the rest of the column. These mistakes are easy to miss but can lead to wrong reports, wrong totals, and awkward conversations. This tool catches all of that before you hit send — in seconds. The best part: Everything happens inside your browser. Your file is never uploaded to a server, so it's safe to use even with sensitive financial data. No signup, no limits, completely free.
