No that capability is not added. Forms controls are the way to go for cross-plaform.

Also, Excel 2004 does not support the VB function Split or Replace (and a few others). Split would require an emulator, Application.Worksheetfunction.Substitute works for Replace.

There are other differences, you'll need to do some testing.

Also, you should look at using Application.PathSeparator rather than a hard-coded "/"

Going forward, if some of your end users are on a Mac, its much easier to
write on the Mac and add cross platform considerations at the end
than it is to
write on a PC and add cross-platform considerations at the end.
