CSV ↔ JSON Converter

Paste or open a CSV and get JSON, or paste an array of objects and get a CSV. Quoted fields, commas inside quotes, semicolons, tabs and Unicode text are all handled properly, and data that cannot become a simple table is explained rather than silently mangled. Nothing you paste or open is uploaded.

Your data is processed in your browser and is not uploaded to Klyro. Pasted text and opened files are read and converted on this page by your own browser. Nothing is uploaded, stored or logged, which makes this safe to use on a real customer export. Files are held only in memory while the page is open. Signed in on Klyro Pro you can save a mapping to your account — the direction, delimiter and options, never the data you converted.
