JavaScript Object Notation
MIME type: application/json
JSON is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It has become the dominant data format for web APIs and configuration files.
JSON supports six data types: strings (UTF-8, double-quoted), numbers (integer or floating-point), booleans (true/false), null, arrays (ordered lists), and objects (key-value pairs). It is defined by RFC 8259 and ECMA-404. Keys must be strings. The format is a strict subset of JavaScript object literal syntax. Common extensions include JSON5 (with comments) and JSONL (newline-delimited).
Paste your JSON into BriskTool's JSON Formatter - it will pretty-print it with proper indentation, validate the syntax, and highlight any errors. No data is uploaded to any server.
