Automating A CSV File Using Excel Object Model
We come across csv files in testing all the time. Usually they are treated as text files for automation. But they can be automated like Excel files just as Windows opens them using Excel.
This is very helpful in some situations, and the way to do it is very simple. Use the Workbooks.Open method with an additional parameter, that is all!!
This is the Format parameter of the Open method which specifies the delimiter in case of opening a text file and 2 specifies that the delimiter used is comma.
