Stop wasting hours fixing messy Excel exports manually. Remove duplicate rows, standardize mixed dates to ISO YYYY-MM-DD, clean phone numbers & emails, and fix broken #REF! formulas in 1 click — 100% locally inside your browser's RAM.
Automatically detect and remove exact or fuzzy duplicate rows and purge empty rows/columns across large .xlsx and .xls workbooks.
Convert mixed European (DD/MM/YYYY), US (MM/DD/YYYY), and text dates into one uniform format, and turn text salaries (45k€) into clean numbers.
Unlike cloud Excel cleaners, your spreadsheet is never uploaded to a remote server. Everything runs locally inside your browser via WebAssembly & JavaScript.
