Possible disadvantages of JSONLint

• Internet Connection Required
  JSONLint is a web-based tool, so it requires an active internet connection to function, which can be a limitation in offline environments.
• Basic Features
  While JSONLint is excellent for simple validation and formatting, it lacks more advanced features like schema validation or integration with development environments.
• No API
  JSONLint does not offer an API for programmatic access, limiting its use in automated workflows and larger development pipelines.
• Ads on the Website
  The website includes advertisements, which can be distracting for users and might affect the user experience.
• Limited Customization
  The tool does not offer much in terms of customization options for how errors are displayed or how JSON is formatted, which might not meet all user needs.
