Cleve, what I did was just select all the cells in Excel, hit 'copy' and pasted it into a .txt file. Then I used a text editor called UltraEdit to convert the tabs to spaces, remove all the trailing spaces, and convert any double spaces to single.
That did the trick pretty quickly.
If you don't have access to a text editor like that, you could email me the text files at clarity at buckeyeplanet dot com, and I could do that part pretty easily.
