Frequently asked questions
Is JSON to CSV free to use?
Yes. JSON to CSV is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does JSON to CSV upload your JSON file to a server?
No. JSON to CSV processes your JSON file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in JSON to CSV.
Do I need to install anything to use JSON to CSV?
No installation is needed. JSON to CSV runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Will JSON to CSV keep the original quality?
JSON to CSV preserves the source content faithfully where CSV supports it. Where the two formats differ, the tool favours visual fidelity over the smallest possible output.
What happens to your JSON file when I close the tab?
It is discarded. JSON to CSV keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
