What it does
Formatting keeps your key order. “Sort keys” recursively sorts object keys so two configs can be diffed. Validation reports the character offset and the line/column of the first syntax error.
Paste JSON, format it, minify it, or find out exactly where it breaks. Everything runs in your browser — nothing is uploaded.

Paste JSON and press Format to get two-space indentation, or Minify to strip all whitespace before you drop the payload into a request. Validate checks the document without rewriting it.
When the JSON is invalid you get the parser message plus the line and column where it failed, which is usually enough to spot a trailing comma, a missing quote or an unescaped newline inside a string.
Sort keys reorders every object alphabetically so two responses can be diffed by eye. Copy puts the result on the clipboard. Nothing is uploaded: parsing runs in the tab with JSON.parse, so credentials and payloads stay on your machine.
