JSON Formatter & Validator
JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate. Use our tool to format, validate, and minify JSON data.
What is JSON?
JSON is a text format that is completely language independent but uses conventions familiar to programmers of the C-family of languages (C, C++, C#, Java, JavaScript, Perl, Python). These properties make JSON an ideal data-interchange language.
JSON Data Types
- Object: Unordered collection of key/value pairs enclosed in braces
- Array: Ordered collection of values enclosed in brackets []
- String: Text enclosed in double quotes "text"
- Number: Integer or floating-point numbers
- Boolean: true or false
- Null: Represents no value
Common Uses
- API responses and requests
- Configuration files
- Data storage and transmission
- Web application state management
- NoSQL database documents
JSON Best Practices
- Use descriptive key names
- Keep structure consistent
- Avoid deeply nested structures
- Use arrays for lists of similar items
- Validate before sending to production
