Hello, I have 40 input files, there are two sets of 20 files each with the same file name for the current month and previous month (I.E. there are two sets of files named File A, File B, File C, etc). Is there a way to combine these in a macro based on the input file name, so File A for the current month would be paired with File A from the previous month? I just need them paired together as I have the tools in place to perform the analysis once they are combined. I would also need these outputted into one combined excel XSLX which has 20 tabs (one for each of the new output data sets, I.E. Tabs are called File A, File B, File C, etc). Thanks so much and if I can clarify please let me know.
