I Built a Free JSON Formatter (Because Postman's Web UI is Clunky)

Описание и применение

Браузерный JSON‑форматтер, работающий полностью офлайн, без регистрации и загрузки данных на сервер.

Задача

Postman's web UI requires an account and uploads JSON to a remote server, posing privacy risks and usability issues for simple formatting tasks.

Результат

The tool provides a free, private, offline JSON formatting and validation experience, eliminating the need for accounts or server uploads.

Рабочий процесс

• Paste raw JSON or drag-and-drop a .json file
• Click "Format" to pretty-print with chosen indent
• Click "Validate" to check syntax and see error locations
• Click "Minify" to collapse JSON to one line
• Use one-click copy to clipboard
