Append to excel file

Mar 29, 2014 at 8:46 PM

I have an excel file (created with ClosedXML library) and I want to append new rows to existing excel file (same format as the original).
I was thinking about reading the original file and get the data, get the new data and save them all together in a file.

Is there other (maybe better) way to do this that I am missing?
