About the JSON Formatter / Viewer
Paste any JSON, then Format to pretty-print it with your chosen indent, or Minify to strip every space and line break. Validate tells you if the JSON is valid and points to the error position when it is not.
The tree view builds a collapsible outline of your data so you can explore deeply nested objects and arrays. Click any object or array node to fold it away, then click again to open it.
Is anything uploaded? No. Parsing, formatting and validation all happen in your browser using the native JSON engine, so your data never leaves your device.
