VALUE-ONLY XLSX EDITOR
Edit workbook values and save a fresh XLSX.
Work across every sheet, fix displayed values, add or remove rows, then download a new workbook. This is a value editor, not a formula spreadsheet.
Open an Excel workbook
Your workbook stays in this browser. Choose an .xlsx file up to 50 MB.
What this tool changes
Workbook bytes stay in your browser. CSV and JSON exports contain the active sheet and visible rows. The editor writes a new value-only XLSX file; it does not preserve formulas, styles, macros, charts, or unsupported workbook metadata.
