Ensure that the date is in the correct format in Excel.  For example, If the month is 007 in the data file, change it to 07. 

To format the cells:
  1. In Excel, right click on the cells and select Format Cells.
  2. Select Date on the left and M/YY as the type.
  3. Save the import file.
Note:Anytime the file is reopened, the csv file drops the format of the cells and the cells must be formatted again. 


If the date is in the correct format in Excel, please make sure that the fields in Excel are mapped properly to the Raiser's Edge Fields before importing.
