<Race>AbilityFunc.txt - does adding this file using MPQ2k cause desyncs?

I have heard adding an .xls (Excel) file can cause desyncs when in BNet, but I have also heard the multiplayer map "SmashTV Acade" was able to use the AbilityFunc.txts without any trouble. Editing this files is quite handy, so I was wondering if anyone had a definate answer, and if so, is there a known way to get around this?

As far as I know "Profiles" -> "Units\Race***.txt" will not cause desync.

Thanks. Editing the "AbilityFuncs.txt" and "AbilityStrings.txt" really adds up a lot of functionality to multiplayer games.
