JSONCraft
Beautify, minify, and validate JSON. Search any key or path, export arrays of objects to CSV, and explore the whole structure as a collapsible tree.
Paste any JSON into the box below, then hitFormat to pretty-print it with 2-space indentation, or Minifyto strip all whitespace. If the JSON is invalid, you'll get an exact error message with the line and column it failed on. Everything runs locally in your browser — nothing you paste is ever sent anywhere.

How JSONCraft works
Format & minify
Pretty-print with clean 2-space indentation, or strip every byte of whitespace for the smallest possible payload.
Validate with precise errors
Invalid JSON returns the exact line and column of the syntax error, so you fix it in seconds instead of scanning a wall of text.
Search keys & paths
Type a key, a value, or a dotted path likeusers.0.email and every match lights up in the tree.
Export to CSV
An array of flat objects becomes a proper CSV with a header row, correct quoting, and a one-click download.
