There are several color-coded tabs in the template file that provide guidance through the import process.  The tab labeled, 'Data Requirements' should be read first before attempting to fill in the templates.  The tab provides charts and information about the required fields for each import. 


All required fields in the templates are labeled.  There are some cells that are not required, and may be deleted before importing the data.  It is important to fill in all required cells, as the file will not upload properly with empty cells.
