Built for everyday technical work

JSON Format Plus started with JSON formatting, then expanded into a compact toolbox for the small checks that happen during API debugging, documentation, data cleanup, meetings, and release preparation.

Useful before decoration

Each page begins with a working browser tool. Supporting text explains when to use it, what the output means, and which limits to review before using the result.

Local-first by default

JSON, text, tokens, names, and timestamps are normally processed in your browser. Pages that need a network request, such as the public IP checker, state that behavior directly.

Readable navigation

Tools are grouped by task instead of hidden behind long SEO lists: data and format, text and encoding, developer utilities, and everyday helpers.

How pages are maintained

  • Keep tools usable without sign-in, installation, or file uploads for common cases.
  • Avoid fake download buttons, ad-shaped controls, popups, and pages made only for advertising.
  • Explain data handling and tool limitations in plain language so users can decide whether a result is safe to reuse.
