• Schema Validation
  The tool supports JSON schema validation, ensuring that the JSON data conforms to a specified structure, which helps in catching errors early.

Possible disadvantages

• Security Concerns
  Given that the tool operates online, there may be concerns about the security and privacy of sensitive JSON data being edited in a web environment.
• Limited Customization
  The editor offers limited customization options for the user interface and functionalities, which may be a drawback for advanced users with specific needs.

• Free and web-based
