JSON Formatter
Format, validate and minify JSON data.
About JSON Formatter
JSON Formatter validates, formats and minifies JSON entirely in your browser, with nothing you paste ever sent anywhere.
Use it to make a minified API response readable while debugging, to catch a syntax mistake with an exact line and column reference rather than guessing where a parser gave up, or to compress a formatted file down before using it somewhere size actually matters.
Formatting and minifying never change the underlying data, only how it is presented, so the same input always parses to exactly the same result either way.
