Excel to JSON

Turn spreadsheets into clean, usable data. Drop an Excel (.xlsx, .xls), OpenDocument (.ods), or CSV file, pick a sheet, and convert it to a JSON array of row objects or to CSV — with pretty-printing and instant download. Parsing runs entirely in your browser with SheetJS, so even sensitive spreadsheets never leave your device.
