JSON to CSV

Convert JSON arrays into CSV files that teams can open in spreadsheets.

A common developer task is taking JSON output from an API or script and turning it into a spreadsheet-friendly CSV export. DataConvertor reads arrays of objects or arrays of arrays, derives columns, and gives you CSV output you can copy or download directly in the browser.

Why developers search for JSON to CSV

JSON is great for APIs, but product teams, support teams, and analysts often need rows and columns. A JSON to CSV tool helps bridge those worlds, especially when you need to flatten a quick export without writing custom code or spinning up a backend job.

Example

JSON
[
  { "id": 1, "name": "Ada", "active": true },
  { "id": 2, "name": "Grace", "active": false }
]

CSV
id,name,active
1,Ada,true
2,Grace,false

What the tool handles

• Collects keys across the whole dataset to build consistent headers.
• Escapes commas, quotes, and newlines for CSV-safe output.
• Stringifies nested objects or arrays so the export stays readable.
• Shows the first 50 rows in a preview table before download.
