What is a JSON Validator?
A JSON (JavaScript Object Notation) Validator is a tool that checks if a given string is valid JSON. It ensures that the text adheres to the strict syntax rules of JSON, such as correct use of brackets, braces, quotes, and commas. This is essential for data interchange between a server and a web application, as JSON is a common format for such communication.
