About the JSON to CSV Converter

Turn a JSON array of objects into comma-separated values you can open in Excel, Google Sheets, or any spreadsheet app. Column headers are collected from every object, and values containing commas, quotes, or line breaks are safely quoted. Everything runs in your browser — nothing is uploaded.

Common use cases

API responses: flatten a JSON payload into a spreadsheet for review.
Data exports: hand CSV to teammates who don’t work with JSON.
Reporting: load records into a sheet for charts and pivots.

How it works

Paste JSON, upload a .json file, or fetch it from a URL.
Click Convert.
Copy the CSV or save it as a file.

Frequently asked questions

What JSON shape does it expect?

An array of flat objects works best. A single object is treated as one row. Nested values are written as-is.

Is my data uploaded?

No. Conversion happens locally in your browser — your data never leaves your device.
