With so many moving parts, it’s easy to lose track of what the formula is actually supposed to achieve. I’ve found LET to be the best fix for this. It’s an Excel function borrowed from programming that makes complex formulas significantly easier to read, write, and maintain, and it hasn’t failed me yet.”
