Haven't been in this NG for a while. Good to be back!

I'm creating an XL spreadsheet from a .NAB file exported from Novell
GroupWise. It's an Address Book group, with names, email addresses, etc
exported from GW. I want to open the .NAB, give it the settings to create
the spreadsheet, then edit the spreadsheet by deleting some columns and
putting in some headers, then saving the file as an XL workbook (.XLS). I
recorded a macro first to get the simple stuff down without writing code
(very rusty here). So far, it's this:

My question is, can I select the file I want to convert, then have the
macro take it from there? As it is now, the macro is using the same file
every time, and I want to tell the macro which file I want it to operate
on. Since XL is immediately processing the .NAB file when I open it, I
don't know how to separate the two operations, the selecting of the file,
and the importing and conversion that automatically takes place.

If this can't be done, my alternative is to open the file and manually give
the conversion instructions, then run the macro to format the file, which
is doable, but I'm Ben Franklin lazy (hate doing repetitive tasks) and
prefer to let XL do as much of the work as possible. Besides, I like
learning new things in VBA.

Can anyone help me along here? TIA.
