How to Convert JSON to CSV Online (Free, No Upload)

Convert JSON to CSV in seconds, right in your browser, with no install and no account.

APIs and apps give you JSON, but analysts and managers want rows and columns they can sort and filter. Reading JSON by eye, or writing a script just to flatten it, takes time.

The converter turns every object in a JSON array into one CSV row. Nested objects become columns such as address.city, and every key found in any record gets its own column, so no data is dropped.

Your file is processed in your browser and is not uploaded to a server, so it is safe to use with customer or business data.
