About

TidyCSV is a small utility that turns JSON into CSV.

You can paste JSON, upload a .json file, or ask your browser to fetch a public http or https URL. Nested objects are flattened into dotted columns, with a short preview before you download the CSV. The conversion itself runs in your browser. There is no account and no upload of the pasted or chosen file to this site.

Who operates it

TARS FUTURE LTD operates TidyCSV.

What it does not do

• It does not convert JSON on a TidyCSV server.
• It does not proxy URL imports. If a host blocks cross-origin reads, the import fails in the browser.
• It does not add analytics, advertising, or a sign-in.
