JSON Formatter

FreeDeveloper & Technical

Format, minify, explore and compare JSON without it leaving your browser. Large files are parsed in a background worker, numbers stay exactly as written, and loose JSON with comments or trailing commas can be repaired.

Features

  • Format or minify, with indentation, key sorting and one-line short arrays
  • A tree view with search, path copying and path queries like $..id
  • Convert between JSON, YAML and CSV
  • Diff two documents, ignoring key order
  • Repair mode for comments, trailing commas, single quotes and unquoted keys

Runs in your browser: your files are processed on your device and never uploaded.
