  3. Download CSV ready for Excel, Google Sheets, or databases

Why convert JSON to CSV?

APIs and apps often export JSON, but spreadsheets and BI tools prefer CSV. Converting locally lets you open data in Excel without uploading sensitive exports to third-party services.

Is this converter safe?

Yes. Your JSON is parsed in-browser — ideal for customer lists, analytics exports, and internal reports.

Frequently asked questions

What JSON shape is supported?

A top-level array of objects works best, e.g. [{"id":1,"name":"A"}]. Keys from the first object become CSV column headers.

Are nested objects flattened?

Nested fields are stringified when converted to cell values. For complex trees, flatten in your app before export.

Is my data uploaded?

No. Parsing and CSV generation run entirely in your browser using JavaScript.
