JSON to CSV Converter
Paste a JSON array of objects and get a properly formatted CSV with a header row, ready to download or paste into a spreadsheet. All conversion runs locally in your browser.
CONVERT
Accepts a flat JSON array of objects. Nested values are converted to strings.
How it works
The JSON array is parsed with the native JSON.parse API, then each object is serialised into a CSV row, with values containing commas or quotes automatically escaped. All processing runs locally in your browser.
Processing runs in your browser
All conversion happens inside your browser tab using JavaScript. Our servers are not involved at any point.

After converting, pretty-print or minify the output with the JSON formatter. For escaping commas or quotes inside cells, try URL encode. To convert formatted SQL dumps into rows, see the SQL formatter.
Frequently asked questions
- What JSON shape does the converter accept?
- A flat array of objects, like [{"name":"Jane","age":30},{"name":"Sam","age":25}]. Each object becomes one CSV row, and the keys become the header.
- How are special characters in values escaped?
- Values containing commas, quotes, or newlines are wrapped in double quotes. Internal double quotes are doubled ("") per the standard CSV escaping rules.
- Can the output open in spreadsheet apps?
- Yes. The CSV uses standard comma delimiters and quote escaping, so it opens cleanly in any spreadsheet application.
- Is my JSON data uploaded anywhere?
- All processing runs in JavaScript inside your browser tab. Our servers are not involved at any point.
