Excel expert David Ringstrom, CPA, teaches you how to identify and manage duplicate data within your spreadsheets in this beneficial presentation. David covers a variety of topics, including identifying duplicate data visually by way of the Conditional Formatting feature, using a pivot table to determine how many duplicates are in a list, and applying worksheet functions like SUMIF or COUNTIF to sum or count instances of duplicates.

David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in Excel 2016. He draws your attention to any differences in Excel 2013, 2010, or 2007 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.
