Common questions
Is it free?+
Yes — convert CSV to JSON free. Paid plans add larger files, batch and priority.
Is my data private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Is the conversion accurate?+
Yes — we use a faithful, lossless engine. Keys, values and nesting are preserved so the output round-trips back to your source.
