XLSX TO JSON

Convert an Excel sheet to JSON.

Select a worksheet, narrow its rows, and download structured objects with deterministic ISO dates.

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.
