Found naming convention issues, data type inconsistencies, and duplicate valuesJSON linting goes beyond basic validation to analyze code quality, style consistency, performance implications, and best practices. It helps you write better, more maintainable JSON.
While validation only checks for syntax errors, linting analyzes code quality, naming conventions, data types, performance, and suggests improvements for better maintainability.
Yes! You can enable/disable specific rule categories like naming conventions, data type checking, performance analysis, and more through the options panel.
No, all linting happens locally in your browser. Large files may take slightly longer to analyze, but your data never leaves your device.
