In this blog, I’ll show you how to use the LET function in Excel to make your formulas cleaner, faster, and easier to debug. The LET function lets you store any calculation or value in a variable, and then reuse it throughout your formula. That means no more repeating long XLOOKUPs or IFs again and again. You’ll learn how to simplify complex formulas, make your logic easier to follow, and even store entire functions inside a variable. If you work with large formulas or want to write smarter Excel calculations, this one’s for you.
