Unlock the full potential of Microsoft Excel 365 by mastering the art of efficient formula writing in this comprehensive course, "Streamlining Formulas with Excel's LET and LAMBDA Functions." Presented by experienced CPA and author David Rangstrom, this session is designed to help you push the envelope on formula creation, enabling you to eliminate repetitive calculations, improve worksheet performance, and create better-documented spreadsheets.

Building on this, you will explore the LET function, a powerful tool that allows you to assign names to calculation results and intermediate values directly within a formula. By using LET, you will learn to streamline complex logic, reduce redundancy, and significantly improve the calculation speed of your workbooks.
Moving beyond standard calculations, the course utilizes the XLOOKUP function as a vehicle to introduce the revolutionary LAMBDA function. You will see how to construct multi-criteria lookups and then convert those complex formulas into reusable custom worksheet functions. The session guides you through the syntax of LAMBDA, handling optional parameters with the ISOMITTED function, and managing these custom functions via the Name Manager. Finally, you will get a glimpse of the Advanced Formula Environment within Excel Labs, a tool designed for writing and editing complex formulas with ease.
By the end of this course, you will possess the skills to:
Note: This course is demonstrated using the Microsoft 365 version of Excel for Windows. While most functionality applies to Excel for Mac, specific features like LAMBDA and LET require Excel 365 or Excel 2021 and later.
