You use the Table To Table and Table To Geodatabase tools to import dBASE, INFO, vector product format (VPF), OLE DB, or geodatabase tables into a geodatabase. These tools are available from the context-sensitive menu in ArcCatalog or from ArcToolbox.
When you import several tables at the same time with the Table To Geodatabase tool, each table imports into a new table. The tool will automatically correct any illegal or duplicate field names.
