About JSON
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. It's widely used for:
- • API responses and requests
- • Configuration files
- • Data storage and exchange
- • Web application state management
- • Mobile app data synchronization
This formatter validates JSON syntax, provides helpful error messages, and can convert between different formats including CSV and XML.
