Excel spreadsheet users often are stopped in their tracks by error prompts that arise from seemingly simple actions. In this unique session, Excel expert David Ringstrom, CPA, digs into the dark corners of Excel to give you the how and why behind many frequently encountered error prompts. You also gain exposure to a number of Excel’s features and learn what to do when Excel seemingly goes awry.

David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the subscription-based Office 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.

Office 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.
