Multiple excel sheets into 1 master

You are really working backwards. Why have separate input sheets & then duplicate data? The best way is to have all the data one one sheet then Excel has various methods to work with that data - AutoFilter, etc

Here's some code that will combine sheets, you may need to adjust it for your specific needs.
