How to convert with this JSON to CSV converter

  1. Open the converter and choose your output format.
  2. Drop your file onto the upload area or choose it from your computer.
  3. Click Start Converting and wait for your browser to process the file.
  4. Download the finished file and review the result before using it.

Why browser-based conversion helps

Your files are processed on this device instead of being sent through a server upload queue. That can be faster for quick jobs and better for private documents, images, and data files you do not want sitting in someone else's storage.

Flat arrays of objects convert best. Deep nested JSON may need cleanup.
