How to upload data from Excel to populate fields on data cards with unique values for multiple files in PDM professional?

I have a list of cross-reference numbers in Excel that I need to upload into PDM Professional (2018) to populate the cross-reference field on file data cards for several existing files in PDM.

Each file (part number) has a unique cross-reference number for it.  The fields exist on the cards, I just need to bring in the data from Excel to populate the cards.

Is there any recommended way to do this?  I have not found any info on this topic in forums, and would appreciate advice on how to do this.  Thanks.
