Frequently asked questions
How are nested objects and arrays converted?
Nested objects become columns named with dots, such as address.city, and arrays are written into one cell as JSON. If the file is an API response with an array inside, that array is used.
Is converting JSON to CSV free?
Yes. Conversion is free, with no sign-up and no watermarks.
Are my JSON files uploaded anywhere?
No. The conversion runs in your browser, so your files never leave your device.
What data is kept when converting JSON to CSV?
All cell values and column headers. Formulas are saved as their calculated results; formatting, charts and images are not carried over, since CSV and JSON store data only.
