Home › Developer & Text Tools › JSON Formatter
Beautify, minify or just validate — with the parser's exact error message when something's wrong, and total privacy for your payloads.
This page opens the Developer & Text Tools with the right mode pre-selected. Eleven utilities, zero uploads: JSON beautify/minify/validate with clear error messages, Base64 and URL encoding both directions, a JWT decoder that shows header, payload and expiry status, SHA-1/256/384/512 hashes via Web Crypto, UUID v4 generation, a timestamp converter handling Unix seconds/milliseconds and ISO dates, a word/character/reading-time counter, seven case conversions including camelCase and snake_case, line tools (dedupe, sort, trim, shuffle), and a line-level text compare with added/removed highlighting.
Decoding happens locally and nothing is transmitted — but as standard practice, avoid pasting live production credentials into any tool, and note that signatures are not verified here.
No — like every iConvertDoc tool, this runs entirely in your browser. Files are processed on your device and never transmitted.
Yes. No sign-up, no limits, no watermark.
