About JSON Formatter
JSON (JavaScript Object Notation) is the most widely used data exchange format in web APIs and configuration files. Poorly formatted JSON is hard to read and debug. This formatter parses your JSON and displays it with proper indentation, making it easy to read, validate, and debug. It also highlights syntax errors so you can find and fix problems instantly.
FAQ
- What is JSON?
- JSON (JavaScript Object Notation) is a lightweight text format for storing and transporting data. It is easy for humans to read and write, and easy for machines to parse and generate. JSON is widely used in web APIs, configuration files, and data storage.
- Why does my JSON show an error?
- Common JSON errors include missing commas between items, unquoted keys, trailing commas after the last item, and single quotes instead of double quotes. JSON requires double quotes for all strings and keys.
- What is the difference between formatted and minified JSON?
- Formatted (pretty-printed) JSON has indentation and line breaks, making it human-readable. Minified JSON removes all unnecessary whitespace to reduce file size, which is useful for production APIs and data transfer where bandwidth matters.
