Creating 1 output tex file from multiple Excel files

[Excel_VBA]

I am trying to use ConvertXLS.EXE from the webpage listed below. I have 4 Excel files with 3 tabs of data each. I am trying to convert to a pipe delimited text file. In the output folder I designate, I end up with 4 files. Not only that, each file pulls data from only one tab.

How do I pull data from all tabs of each file, and combine all 4 files into just one Text file as an output, so that I have 12 tabs worth of data in one Text file? Is this even possible?
