Preparing GTM-Compatible CSVs

GTM cannot process the downloaded files directly since they do not contain GTM columns like gid/xid, domain_name, insert_date, update_date, etc. The data load process parses these files and creates GTM-specific CSV files that are formatted to load data directly into GTM tables.

The following sections provide the data mapping between the expected data provided by the content provider and GTM. If an element appears in the raw sample but is not listed below, it is not used by GTM.
