Anyone here use "Exact Change" as their collection spreadsheet?

There's a thread on the US side about software, this program looks like it could be very good for non-US coins, currency, even medals/exonumia. The idea of learning to finally make a fully featured Excel (or similar) spreadsheet is mind boggling, and this program looks VERY interesting.

I worry about what happens in a decade or two though in terms of becoming obsolete. Unless the developer is at least 10 years younger than me, has an excellent family history for longevity and mental acuity, and has a few partners who might take over the program eventually....
