I create a report weekly. I use Power Query to get the data from a number of new Excel files (Dimension reports). Each file has a number of records. When I load to the spreadsheet, I lose the file name and modified date. I can't really create a one to many relationship (I think?) because it is new data every week.
Is there a way to keep the identifying information with the data?
Thanks
Willy
