This is involved; you need to do some manual steps that normally will be handled by the assembler - but the editing capabilities are unbeatable: copy, paste, move, swap, replace, hyperlinks...

A coworker of mine also used Excel to build an assembler for the 8051. I'm rather curious about this use of Excel. Sadly my coworker passed away some years ago.

Does your environment generate the final .bin/.mod file? Manages both FOCAL and assembly programs? I'm not developing anything for the 41 but, as I said, I'm just curious.
