Presenter: David Ringstrom, CPA
In this presentation, author and Excel expert David H. Ringstrom, CPA will guide you through building a lease tracker from the ground up using Microsoft Excel. You'll discover how to structure lease data effectively, apply data validation to reduce input errors, and calculate lease durations using the DATEDIF function. David will demonstrate how to flag upcoming expirations, highlight critical leases, and summarize your lease portfolio with PivotTables. You’ll also learn how to protect your worksheet and create dynamic drop-down lists to streamline lease management. Whether you're new to lease tracking or looking to refine your existing process, this session offers practical, hands-on tips to help you manage lease agreements with confidence and clarity.
David is the author of “Microsoft Excel 365 for Dummies”, “Exploring Microsoft Excel’s Hidden Treasures”, and has written or co-authored six other books. 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.
