David H. Ringstrom

author and Excel expert

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 courses.
