In this presentation, author and Excel expert David H. Ringstrom, CPA, will cover a range of topics to enhance your Excel skills. You will learn how to assign names to cells, which lays groundwork for the LET and LAMBDA functions. The LET function is available in Excel 2021 and Excel for Microsoft 365 and enables you to create pairs of names and associated values that can store intermediate calculations. David will address common issues such as the #NAME? error with the LET function and then introduce the LAMBDA function available in Excel for Microsoft 365, which enables you to create custom, reusable worksheet functions without writing programming code. He will also demonstrate the ISOMITTED function and showcase the Excel Labs Add-In. Additionally, you will discover how to save LAMBDA functions to GitHub and download them from there. David will guide you through the advanced formula environment and provide insights on moving LAMBDAs between workbooks. Don't miss this opportunity to expand your Excel expertise.

David is the author of “Exploring Microsoft Excel's Hidden Treasures: Turbocharge your Excel proficiency with expert tips, automation techniques, and overlooked features”. He demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the subscription-based Excel for Microsoft 365. David draws your attention to any differences in Excel 2021, 2019 or 2016 during the presentation and in his detailed handouts. The handouts include an Excel workbook with most of the examples he uses during his demonstrations. Excel for Microsoft 365 is a subscription-based product that receives periodic feature updates. Conversely, perpetually licensed versions have year numbers in their names and do not receive any feature updates.
