🎯 What is API Response Formatting?
API response formatting is the process of converting minified or unstructured API responses into readable, well-formatted text with proper indentation and syntax highlighting. This makes it easier to debug, understand, and work with API data.
Why format API responses? Raw API responses are often minified to reduce bandwidth, making them difficult to read. Formatting improves readability, helps identify errors, and makes it easier to understand the data structure.
Multiple formats: Our formatter supports JSON, XML, YAML, and CSV formats with automatic detection and validation.
