JSON Formatter

JSON (JavaScript Object Notation) represents data as nested objects and arrays, but when it comes from an API response, a build log, or a minified config file, it's usually delivered as one long line with no spacing. That's efficient for machines to parse but nearly impossible for a person to scan. A formatter reindents the same data with consistent line breaks and spacing — typically two spaces per nesting level — so brackets line up and it's obvious which value belongs to which key.

This is most useful when debugging: pasting a raw API response here turns an unreadable wall of text into a structure you can actually scroll through and reason about, making it much easier to spot a missing field or an unexpected null. It's also handy for cleaning up JSON before committing it to a repository as a config file, since most style guides expect readable, indented JSON rather than a single compressed line.

Formatting only changes whitespace — it doesn't reorder keys, convert types, or validate anything beyond the syntax needed to parse the document. If the input isn't well-formed JSON, formatting will fail with an error rather than guessing at the intended structure.
