It also shows data types (string, number, boolean, null, object, array) for each value, making it easier to understand your data structure at a glance.

JSON Formatting Tips

Always validate your JSON before using it in production applications
Use proper indentation (2 or 4 spaces) for better readability
Minify JSON for API responses to reduce payload size
Use descriptive key names that clearly indicate the data they contain
Keep JSON structures consistent across your application

Common JSON Errors to Avoid

Missing commas between object properties or array elements
Trailing commas after the last item in objects or arrays
Unquoted keys (keys must be strings in JSON)
Single quotes instead of double quotes for strings
Comments (JSON doesn't support comments)
Undefined values (use null instead)
