I have 4 excel files of same headers
i have 2 excel files of same headers
So i will merge them and output will be 2 excel files say Excel A and Excel B
Now there are 2 master files
And at last i have 1 Output file
The columns or the index place of the column headers arent matching

Now i want to get all the data from those excel files and map it to output file
And if any cell get empty then mark it red
And then send mail saying this particular records column is empty
How do i do it
