Learn how to minimize errors in your Excel spreadsheets from Excel expert David Ringstrom, CPA. In this valuable presentation, he shares a variety of tricks and techniques you can implement to create and maintain spreadsheets that are free of errors. David demonstrates how to implement Excel features and functions, such as the Hide and Protect feature, the Conditional Formatting feature, the VLOOKUP function, the SUBTOTAL function, and others. In addition, he discusses how to preserve key formulas, perform dual lookups, audit the spreadsheets created by others, and more. David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the 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.
