JSON to Excel (XLSX) Converter

Paste a JSON array of objects below to download a real Excel workbook (.xlsx) - useful for handing API data or exported records to someone who works in spreadsheets, not code.

Nested JSON fields are flattened into columns automatically, the same way as the JSON to CSV converter, just packaged as a proper .xlsx file.

Secure & Private: Your data is sent to our server only to perform the conversion, then immediately discarded — nothing is logged or stored.

Frequently Asked Questions

What if my JSON is a single object, not an array?

Wrap it in square brackets ([ ... ]) so it’s an array with one item - the converter expects an array of records to build spreadsheet rows.
