I have several Excel workbooks that all use the same VBA code. Rather than place the same code in each workbook file, I would like to place the VBA code in a single external text file and have each workbook reference and call the VBA code in that file. In this way, if the code needs to change, I can change the code in just one place rather than having to change the code in each Excel file. Note that I cannot combine the separate Excel workbooks into one workbook where each Excel file is a separate worksheet.) How can separate Excel workbooks call the VBA code in a single external file?
