TextArray vs JSONFormatter.org

Updated August 26, 2026

JSONFormatter.org is a JSON formatter and validator surrounded by roughly a hundred related converters. It states that "your JSON data gets validated in the browser itself", which is the right way round, and it is funded by advertising: "Ad blocking? It's okay. Please share to support us."

It also has an optional login, with a caveat worth reading: "if JSON data is saved without login, it will become public."

Where JSONFormatter.org is strong

  • Validation genuinely happens in the browser, by the site's own account.
  • A large surrounding catalogue of converters between JSON, XML, YAML, CSV and language classes.
  • Shareable saved links, which TextArray has no equivalent for.

TextArray formats, minifies and validates JSON with the exact line and column of any error, renders it as a tree, sorts its keys, flattens it to dot notation, diffs two documents by path, and converts it to TypeScript, Go, Rust, C#, Java, Python, Zod, Protobuf, GraphQL SDL, CSV, XML, SQL and .env. None of it is saved anywhere, so there is no public-by-default footgun.

There is also no advertising. On a page where the paste is often a production API response, third-party ad scripts running in the same document is the part worth thinking about — and the reason TextArray fails its own build if any request other than a cookieless analytics beacon appears.

FAQ

Does JSONFormatter.org upload my JSON?
It states that validation happens in the browser. Saving a link is different: the site warns that data saved without logging in becomes public.
Can TextArray share a formatted document?
Only through a link that carries the text in the URL fragment, which never reaches a server. There is no stored, shareable copy — by design.
Which handles a large payload better?
TextArray accepts up to 10 MB and has a tree view built for reading a large document. Both do the work locally, so it comes down to the interface.
