How to Format and Validate JSON

JSON is the standard data interchange format for APIs and configuration files. Proper formatting makes debugging significantly easier.

Formatting

Use 2-space indentation for readability. Keep arrays and objects on separate lines for complex structures.

Validation

Always validate JSON before deployment. Common errors include trailing commas, unquoted keys, and single quotes instead of double quotes.

Tools
