David Ringstrom, CPA, shares a variety of tricks and techniques you can employ to improve the integrity of your Excel spreadsheets as well as to audit the spreadsheets created by others. In this empowering session, he presents simple ways to prevent errors from being introduced into Excel workbooks. In addition, David explains the benefits and uses of several Excel features and functions, including the Hide and Protect feature, the Conditional Formatting feature, the VLOOKUP function, the SUMIF function, and more.

David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the Microsoft 365 (formerly known as 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.

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.
