Presenter: David Ringstrom, CPA
In this presentation Excel expert David H. Ringstrom, CPA builds on the concepts shown in Part 1 of this series by showing you how to use pivot tables to summarize your CAM results. He will also show how to create gross-up calculations in Excel.
David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the subscription-based Microsoft 365 version of Excel. David draws your attention to any differences in the older versions of Excel (2019, 2016, 2013, and earlier) during the presentation as well as in his detailed handouts. David also provides an Excel workbook that includes most of the examples he uses during the webcast.
Microsoft 365 is a subscription-based product that provides new-feature updates as often as monthly. Conversely, the perpetual licensed versions of Excel have feature sets that don’t change. Perpetual licensed versions have year numbers, such as Excel 2019, Excel 2016, and so on.
