A JSON validator typically checks for several things, such as:
- Correct syntax: The JSON file follows the correct syntax rules, such as proper key-value pairs, comma separation, and correct data types.
- Well-formedness: The JSON file has a well-formed structure and follows the correct nesting rules.
- Missing or extra characters: The JSON file does not contain any missing or extra characters.
- Validity of the data: The JSON file contains valid data based on the specification.
There are various online JSON validators available, such as Oumify.
Also, many code editors have built-in JSON validators or have the ability to install a plugin to provide this functionality.
It's important to note that a JSON file that passes validation may still contain errors or be invalid for a specific use case. As a result, it is recommended that the JSON file be validated and tested in the intended system or application.
