Private by design
CSV ⇄ JSON runs 100% in your browser. Your files are never uploaded to a server, never stored, and never seen by anyone — close the tab and nothing remains.
Free, no limits
CSV ⇄ JSON has no account, no watermarks and no daily caps. If you also need full design tools, the Ijodly editor is one click away.
