Master advanced techniques to eliminate redundancy, improve formula readability, and build reusable custom functions for more efficient spreadsheets.
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.
The course begins by establishing a strong foundation with Named Ranges. You will learn how to define, apply, and manage names for cells and ranges, transforming cryptic cell references into intuitive, readable data points. This functionality serves as crucial scene-setting for understanding the more advanced features of modern Excel. 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.

Provincial regulators of CPAs in Canada do not require that independent providers of CPD be approved to offer courses. Instead, individual CPAs are responsible for assessing whether a CPD activity meets their requirements, and may take activities from any source provided those requirements are met.
Every course offered on LearnFormula is delivered by a qualified subject matter expert or learning organization, and advances learning objectives that are relevant to the responsibilities or professional competencies of Canadian CPAs. All activities on LearnFormula are quantifiable in terms of hours, and are also verifiable, in that users receive documented evidence of their attendance via a certificate of completion after finishing a course (and this certificate is stored by LearnFormula indefinitely). Nearly 100,000 Canadian CPAs successfully satisfy their CPD requirements via LearnFormula on an annual basis.
