JSON Beauty Formatter

JSON Formatter is an extension for printing JSON and JSONP nicely when you visit it 'directly' in a browser tab.

Features ● JSONP support ● Fast, even on long pages ● Works on any valid JSON page – URL doesn't matter ● Syntax highlighting ● Collapsible trees, with indent guides ● Clickable URLs ● Buttons for switching between raw and parsed JSON ● Parsed JSON is exported as a global variable, json, so you can inspect it in the console A background worker is used to prevent the UI freezing when processing very long JSON pages.

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
