Paste or drop a JSON file and Jsontify parses it immediately into a searchable tree, a raw text pane, and a details inspector - no upload, no waiting on a server round trip. Click Format to pretty-print the document with your choice of 2 or 4-space indentation, or Minify to collapse it to one line for pasting into a config file or API payload.
Formatting never touches your original text until you explicitly ask for it. Paste stays exactly as pasted; Format and Minify are single, undoable edits, so pressing Cmd+Z (or Ctrl+Z) always gets you back to the exact bytes you started with.
Large files are the actual differentiator here. Jsontify tokenizes and parses JSON in a background worker using typed arrays instead of building a full JavaScript object tree, so a 10 MB file parses in well under a second and a 100 MB file stays scrollable instead of locking the tab. Numbers are re-emitted from their original source lexeme, not round-tripped through a JavaScript number, so a 20-digit integer or a long decimal survives Format and Minify byte-for-byte.
When Format is disabled, it usually means the document has a syntax error - the status bar and the Explorer panel both show the exact line and column, and the Repair button (see the JSON Repair tool) can usually fix it in one click.
