Course Description

In this course, Excel expert David Ringstrom, CPA, shows you how to find and manage duplicate data within your spreadsheets. He explains how to identify duplicates by way of the Conditional Formatting feature; summarize data based on a single criterion and/or a partial match; and apply worksheet functions, such as SUMIF, COUNTIF, and MATCH, to sum or count the instances of duplicates.

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. David draws your attention to any differences in the older versions of Excel (2021, 2019, 2016 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 course.

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.
