Common use cases
- Debug API responses: format into a tree, click nodes to collapse/expand, and locate fields fast even in large payloads.
- Check config files: formatting validates syntax and pinpoints errors to line and column.
- Sort keys to make diffs cleaner for structurally-similar configs; Escape/Unescape handles JSON strings embedded in logs or code.
- Minify for production: strip indentation and reduce transfer size.
