Sending JSON to a recipient who can't open them

When the file format itself is the problem — and JSON to CSV fixes it without explanation. Browser-based, free, no signup, runs entirely on your device.

JSON and CSV both have their place — but when you need one and you've got the other, JSON to CSV is the cleanest way to convert between them in your browser.

Use the tool: JSON to CSV — No upload, no signup, no daily limit.

Why convert before emailing

JSON files are often larger than they need to be for inline viewing. Converting to CSV can drop the size by 30-70%, which puts emails comfortably under attachment limits and renders faster on the recipient's end.

Browser-only. Nothing is sent to a server.

Frequently asked questions

What JSON variants does JSON to CSV support?

Can I convert in bulk?

Yes — drop multiple files; JSON to CSV processes them all with the same settings.
