Human readability – You can open, easily understand, and modify the contents of both YAML and JSON files in any text editor. The two key reasons these formats are heavily used in application development – YAML on the other hand is mainly used for maintaining configuration files and storing data for offline processing.īeing a superset of JSON, YAML offers much more capabilities, but on the contrary, most developers are aware of and use JSON whereas YAML is not so popular. YAML is a strict superset of JSON, which essentially means that all JSON files are also valid YAML files but all YAML files are not valid JSON files.įrom a practical usage perspective, JSON is majorly used for interchanging data between web applications over the internet via APIs.
