About the JSON to Excel converter

This free online json to excel (xlsx) converter lets you turn JSON into Excel in seconds, right inside your browser. There is nothing to install and no account to create — just paste or upload your JSON, and your Excel is generated instantly.

Unlike many online converters, QuickConvert never uploads your data to a server. Every conversion runs locally using JavaScript, so your files stay private on your own device. That makes it safe for sensitive, proprietary, or internal data that you would not want to send to a third party.

Why use QuickConvert?

  • Private by design — your JSON is processed in your browser and never leaves your computer.
  • Fast — conversions happen instantly as you type, with no waiting on a server round-trip.
  • Free & unlimited — no signup, no paywall, no file-size gimmicks.
  • Works everywhere — any modern browser on desktop, tablet or mobile.

Frequently Asked Questions

Is the output a real .xlsx file?

Yes — it is a genuine Excel workbook generated in your browser, not a CSV renamed. It opens natively in Microsoft Excel, Google Sheets, LibreOffice and Apple Numbers.

How are nested objects handled?

With flattening enabled, nested keys are expanded into dot-notation columns (e.g. address.city) so the spreadsheet stays flat and readable.

Is there a row limit?

There is no hard limit, but because everything runs in your browser, very large datasets (hundreds of thousands of rows) depend on your device’s memory.
