You can import data using the menu item "Import" only for Customer, Vendor and Products from Excel files with any structure . At first indicate a source file and then in the opened table select approaching fields having clicked on the grid header. Each Excel file must contain a column with unique numbers of the customers or vendors or products.During the import process the GoInSy looks for unique number values. These records are then imported into the GoInSy database. If the unique value already exists, it skips that record so that you do not get duplicates.
