Format and troubleshoot JSON data
JSON is a text format used by APIs, configuration files and web applications. Valid JSON requires double-quoted property names, supported values and correctly matched braces and brackets. The validator reports the parser error when the input is invalid.
Formatting versus minifying
Formatting adds indentation and line breaks for people. Minifying removes optional whitespace for smaller payloads while preserving the same data.
Is pasted JSON uploaded?
No. Parsing and formatting run in your browser.
