What format must the Global Find and Replace Rules be written in?

The Global Find and Replace Rules must be written in the .YML format, which stands for YAML (YAML Ain't Markup Language). YAML is a human-readable data serialization format that is commonly used for configuration files and data exchange between languages with different data structures.

In the context of Copado and Salesforce, using the .YML format allows for a clear and structured way to define rules that will guide the find and replace operations across metadata. YAML's readability is beneficial for users to easily interpret and modify the rules as needed.

Other formats like .TXT, .JSON, and .XML do have their own use cases, but they do not conform to the specific requirements laid out for Global Find and Replace Rules within Copado. For instance, while .JSON is structured and machine-readable, it is less straightforward for humans to read compared to YAML, making .YML the preferred choice for this particular application. XML, on the other hand, is more verbose and often requires more complex parsing, which can complicate simple find and replace operations.
