I am trying to build a vocabulary file based on Mastronarde's book "Introduction to Attic". I was able to make a copy of gntvoc, change the name of it and convert to an Excel file. I am editing that Excel file with the Mastornarde's vocabulary. My problem is I do not know how to convert the excel to either a .vrt or .vrc. Is there better instructions on how to do this than what is in the Bibleworks help file? I'd be thankful for any help on this.
