What Is JSON Linter?

This tool lints your JSON data and reports style issues such as duplicate keys, inconsistent naming conventions (camelCase vs snake_case vs kebab-case), mixed indentation, and formatting problems. It helps you maintain a consistent JSON style across your project.

How to Use

  1. Paste your JSON data into the input field.
  2. Click "Lint JSON" to analyze the data for issues.
  3. Review the lint report with warnings and suggestions for improvement.

Frequently Asked Questions

Can duplicate keys be detected?

Yes, duplicate keys at the same level are detected and reported as warnings since most parsers use the last value.

Does the linter fix issues automatically?

No, the linter only reports issues. Use the JSON Repair or JSON Formatter tools to fix common problems.
