I have a folder that contains several Excel files I want to combine into one table. However, the week and year that the individual files refer to are only contained in the file names, not in the files themselves. Therefore, I have no way of knowing the week and year that a row of data belongs to when I aggregate the files using the Excel data source. Is there a way to aggregate all Excel files in the folder while also keeping information about which file a record came from? Or is making a separate data source for each file the only solution to keep this information?
By the way, the Excel files are stored on a server requiring username and password, so the TimeXtender Excel data source is (currently) not an option.
