When exporting the table of a feature class with coded value domain descriptions in ArcMap, the coded value is displayed instead of the descriptions.
This is a known limitation. ArcGIS, by default, exports domain codes instead of domain descriptions.
Select one of the solutions shown below. Option A allows the particular table to display the coded value domain descriptions, whereas Option B allows all tables exported to display the coded value domain descriptions. Option C can be used to display both coded domain values and descriptions.
Change the Environment settings, and use the Table to Table tool.
Note: Option C adds a new field for domain descriptions. For more information on exporting a feature class to a shapefile containing domain descriptions instead of domain codes, refer to the following article, HowTo: Export a feature class to a shapefile that contains domain descriptions instead of domain codes.
