问题 I am having a super hard time trying to import multiple Excel files into a specific Access 2013 table. I tried using the code I found from another SO question: Do While Len(strFile) > 0 DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel9, _ strTable, strPathFile, blnHasFieldNames Loop but this makes new tables for each file, and I need all 101 files to be in a single table.
