Financial models can be built efficiently using Excel's dynamic array formulas (FILTER, XLOOKUP, UNIQUE, SORT) to handle complex calculations like revenue growth with seasonality, expense tracking, and multi-criteria lookups, while maintaining model integrity through proper cell formatting, validation checks, and clear separation of input, calculation, and output sheets.
