Great question! Quite often in financial models, you're dealing with "dimensions" (e.g. your revenue is broken down by product, geography, and time). To model this in Excel you have to write complex SUMIF/INDEX/MATCH formulas. Then you have to drag these formulas over 1000s of cells (if you make a mistake you're screwed, see https://eusprig.org/research-info/horror-stories/).

Causal's building blocks are "variables" and "dimensions" which makes it much more powerful to work with dimensional data.
