What is the API Response Formatter?
The API Response Formatter is a must-have tool for backend developers, frontend engineers, and quality assurance testers. Often, APIs return data in massive, unformatted, and deeply nested strings that are impossible to read with the naked eye. This tool takes raw, minified JSON or XML data and formats it with proper indentation, syntax highlighting, and foldable nodes. It drastically accelerates debugging workflows by allowing you to easily visualize data structures and pinpoint specific values.
