JSON to Excel Converter
Turn a JSON array into a downloadable .xlsx spreadsheet

What is JSON to Excel?
Paste a JSON array of objects and download a real Excel .xlsx workbook in one click. Columns are detected automatically across all records, numbers and booleans keep their native cell types, and nested values are serialized safely. Ideal for handing API data to non-technical teammates or importing into reporting tools.

- Adjust the options in the toolbar if needed (root name, format, delimiter …).
- Click the convert button — the Excel output appears instantly in the output pane.
- Copy the result with one click or download it as a file.
