Frequently Asked Questions
What is JSON linting?
JSON linting goes beyond basic validation to analyze code quality, style consistency, performance implications, and best practices. It helps you write better, more maintainable JSON.
How is this different from JSON validation?
While validation only checks for syntax errors, linting analyzes code quality, naming conventions, data types, performance, and suggests improvements for better maintainability.
Can I customize the linting rules?
Yes! You can enable/disable specific rule categories like naming conventions, data type checking, performance analysis, and more through the options panel.
Will linting impact performance?
No, all linting happens locally in your browser. Large files may take slightly longer to analyze, but your data never leaves your device.
