What I would do is import the whole file into a Blank Worksheet - then
delete what you don't want and then copy and past what you do want into
your "Master Sheet"

As for the formula something like the following should work
=IF(D3=E3,D3+F3,"ignore")
Reads as follows If D3=E3, then if TRUE D3+F3, If false then "ignore"
or whatever you want to put into the cell.
