Field aliases are used to __________ data

Cleaning data is the role of transforms and field extractions or the eval command, not field aliases, which only create alternate names without modifying values.

Transforming data involves changing field values or structure, which is done with commands like eval or lookup, not field aliases.

Calculating values is the function of eval expressions or calculated fields, not field aliases, which simply map one field name to another without performing any computation.

Field aliases normalize data by allowing you to assign an alternate name to an existing field, enabling events from disparate sourcetypes that use different field names for the same concept to be correlated and searched uniformly.
