What is JSON Formatter?

JSON (JavaScript Object Notation) is a lightweight data format used for exchanging data.

Pretty Print — Adds indentation and line breaks to improve readability.

Minify — Removes unnecessary whitespace and line breaks to reduce size.

• Automatically highlights the location of syntax errors (line, column).

• This tool runs entirely in your browser — no data is sent to the server.
