I have a folder of 90 excel files each named according to the date of the data within and where the single worksheet in each file has the exact same name. I need to combine the worksheets into a single worksheet, which I can easily do, but I need to differentiate among the data from the various sheets
Workbook1 named 12-2015.xlsx
Worksheet named Detail
Cust_ID Net_Sales
1023 $80
1027 $150
Workook2 named 01-2016.xlsx
Worksheet named Detail
Cust_ID Net_Sales
1023 $100
1027 $175
I need all the data combined on one sheet along with the date of the date (the Workbook name)
