How to Convert JSON to CSV (Free)
JSON is great for code but awkward in a spreadsheet. Converting an array of JSON objects to CSV gives you rows and columns you can open anywhere — here's the fast, private way.
Last updated: July 2026
To convert JSON to CSV, your JSON should be an array of objects — each object becomes a row and each key becomes a column header. Paste it into a JSON-to-CSV converter and it flattens the objects into comma-separated rows you can open in Excel, Google Sheets or Numbers. This runs in your browser, so your data is never uploaded.

Step by step
- Open the free JSON to CSV tool.
- Paste a JSON array of objects.
- Let it map keys to column headers automatically.
- Copy or download the CSV and open it in your spreadsheet app.
What JSON shape converts cleanly?
An array of flat objects with consistent keys converts best — e.g. [{"name":"Ada","age":36}, …]. Each object is a row; each key is a column. Deeply nested objects or arrays inside a field don't map neatly to a single cell, so flatten them first if you can.
Will it open in Excel?
Yes. CSV (comma-separated values) opens in Excel, Google Sheets, Numbers and most databases. If a field contains commas, it's wrapped in quotes automatically so columns stay aligned.
