I did some stuff like this a few years ago - It's not directly from xls to adif, but rather csv to adif, so should be able to work with excel or really any spreadsheet. Details are here:

It's just a basic perl script, but pretty flexible and I built it around satellite contacts specifically.

So I have 4 pages of contacts I need to log, and I'm dreading it. I figured I may as well do myself a favor and write a spreadsheet that spits out an ADIF file so that I don't have to create the ADIF with TQSL (which I despise). I don't use any other logging software, either - just pen and legal pad (actually it's engineering paper this time).
Before I embark on this journey of frustration, has anybody already created a satellite friendly excel (or better - libre office) file that converts multiple contacts into a single ADIF? Otherwise I'll share mine when I'm eventually done (I have found a bunch that are non-satellite friendly).
