How to convert JSON to CSV
- Paste a JSON array of objects.
- The CSV output updates automatically.
- Copy or download the CSV file.
What JSON shape is supported
This tool expects a JSON array of flat objects, like [{"name":"Ann","email":"ann@example.com"}]. Column headers are collected from every object's keys, and nested objects or arrays within a field are converted to their JSON text representation in that cell.
Common use cases
- Convert an API response into a CSV for a spreadsheet
- Turn JSON test data into CSV for import elsewhere
- Quickly flatten a JSON array into rows and columns
Frequently asked questions
Is this tool free?
Yes. It is completely free, with no signup and no limits.
Is my JSON data uploaded anywhere?
No. Conversion happens entirely in your browser.
What if my objects have different keys?
All unique keys across every object become columns; missing values are left blank in that row.
Does this handle commas and quotes inside values?
Yes. Values containing commas, quotes, or line breaks are automatically quoted and escaped per standard CSV rules.
Can I convert a single JSON object instead of an array?
Wrap it in square brackets to make it a one-item array, e.g. [{"name":"Ann"}].
