JSON Formatter
Format, validate, and beautify your JSON data structures for maximum readability and debugging.
About this tool
JSON (JavaScript Object Notation) is a data interchange format used for transmitting structured data between servers and web applications. To optimize bandwidth, systems often transmit JSON payloads as a continuous string without whitespace (minified). While parsable by machines, an unformatted JSON string is difficult for a person to read.
This JSON Formatter transforms minified JSON strings into an organized tree structure by applying indentation and line breaks. It also serves as a syntax validator; if the payload is missing a comma, bracket, or quotation mark, the tool will locate the syntax error. This tool is free to use and requires no registration.
All parsing, formatting, and validation operations are executed client-side within the browser. The payloads are not transmitted over the network.
