Paste, format, and explore JSON data in a tree view

Instructions

  1. Paste JSON text into the input pane, or click "Upload file" to load a .json file.
  2. Click "Beautify" to pretty-print the JSON, or "Minify" to compact it.
  3. Switch between Tree and Formatted views to inspect the data.
  4. Click "Copy" to copy the current text to your clipboard.

Note: Invalid JSON is flagged with an error message, and the tree/formatted views only render once the input parses successfully.
