What is a JSON formatter?
A JSON formatter takes minified or messy JSON and adds indentation and line breaks so it is readable. This one also validates as you type, flags every error by exact line and column, and offers a collapsible tree view, 100% in your browser with nothing uploaded. Also called a JSON beautifier, JSON pretty printer, or JSON indenter.

How do I format JSON?
Paste your JSON into the left pane. If it is valid, the right pane shows it formatted with consistent indentation and line breaks. Choose two spaces, four spaces, or tabs, or switch to minify to strip all whitespace into a single line.
