Excel Explained: Building Error-Proof Spreadsheets Webinar


David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the subscription-based Microsoft 365 (formerly Office 365) version of Excel. Differences in the older versions of Excel (2021, 2019, 2016 and earlier) will be pointed out, as well as in his detailed handouts. He 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 2021, Excel 2019, and so on.
