JSON Escape Online works by taking a JSON string as input and replacing any special characters with their escaped equivalents, which are represented using backslashes. For example, a quote character ("") would be escaped as ", and a backslash () would be escaped as \. This ensures that the JSON string is properly formatted and can be parsed without errors.
JSON Escape Online is useful for web developers and anyone else who works with JSON data frequently. It can help ensure that the JSON data is properly formatted and structured, which can help prevent errors and bugs in your code. It is also useful for debugging JSON data and troubleshooting any issues that may arise.
