how to import data(from Sheet 1) from multiple excel files to multiple columns of a single tablesql tables

I have a specific task and trying to figure out a solution ..
I have a client folder that gets loaded with an excel file for every month. It has multiple sheets but I need to pull just 1 sheet(same columns) from every excel file and load in to a same table.

Every sheet has 2 columns (State and Col2).

Month1

Month2

and so on..

Col 2 is the percentage column which I need to load to database to calculate average on that column and report.
Can you please guide how to perform this task.

Thanks in advance
