How to use
Drop an Excel, OpenDocument, or CSV/TSV file. Pick a sheet (if the workbook has several), choose an output format, and copy or download the result. CSV, TSV, and JSON export the selected sheet; XLSX and ODS export the whole workbook. Everything runs in your browser — no file is ever uploaded.
