JSON to CSV, in your browser

When data lives in JSON — an API response, an export, a config — but you need it in a spreadsheet (Excel, Google Sheets, Numbers) for analysis, reporting or sharing with non-technical colleagues, CSV is the bridge. Mynify converts an array of JSON objects into a clean, comma-separated file on your device, so nothing is uploaded.

How it works

Give it an array of objects and Mynify uses each object’s keys as the header row and each object as a data row, correctly quoting any values that contain commas, quotes or line breaks so the CSV stays valid. A single object works too and becomes one row. Objects with slightly different keys are handled gracefully — the header covers all the keys it sees, and any missing values come out blank.

When to use it

Tip

Going the other way? CSV to JSON turns a spreadsheet export into a JSON array for apps and APIs.

Free, unlimited, no signup, no watermark — converted entirely on your device.

Frequently asked questions

What JSON shape does it expect?

An array of objects — like `[{"name":"Ada","age":36}, …]`. The object keys become the CSV header row and each object becomes a row. A single object also works and becomes one row.

What if objects have different keys?

The converter builds a header from the keys it finds, so mismatched objects still convert — missing fields simply come out blank in that row.

Is my data uploaded?

No — the conversion runs entirely in your browser, so your data never leaves your device.
