What does the parameter label do in Looker?

The label parameter in Looker is used to set the names that appear in the field picker for a given dimension or measure. By assigning a custom label, developers can ensure that the field names presented to users in the interface are clearer and more user-friendly, enhancing the overall experience when building reports or dashboards. This customization allows for improved understanding and brand alignment, as developers can provide names that reflect business terminology or user expectations instead of raw database field names.

While other parameters might influence field types, visibility, or organization, the specific role of the label parameter is to define how fields are displayed to users, making it easier for them to find and use the data they need.
