Possible disadvantages of JSONLint

  • Internet Connection Required

  • 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.
