About JSON Formatter
A JSON formatter takes raw, hard-to-read JSON — often a single long line from an API response or a log file — and pretty-prints it with consistent indentation so its structure becomes obvious. It also works as a validator: if the input isn't valid JSON, you'll see exactly what's wrong instead of a silent failure. The Minify mode does the reverse, stripping all whitespace to make a payload as small as possible before you ship it.

2
Pick Beautify or Minify
Beautify pretty-prints with 2-space indentation. Minify strips every unnecessary character.
