In this presentation author and Excel expert David Ringstrom, CPA, shows you how to create and remove duplicate data in Excel. You'll see mouse tricks for quickly duplicating rows, columns, and entire worksheets, as well as duplicating formatting to disparate cells. David will demonstrate the nuances of duplicates when using lookup functions, and how to easily identify duplicate data with the Conditional Formatting feature. You'll also see how to use the Data Validation feature to prevent users from entering duplicate values into specified cells.

David is the author of “Microsoft Excel 365 for Dummies”, “Exploring Microsoft Excel’s Hidden Treasures”, and has written or co-authored six other books. He demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in the subscription-based Excel for Microsoft 365. David draws your attention to any differences in Excel 2021, 2019 or 2016 during the presentation and in his detailed handouts. The handouts include an Excel workbook with most of the examples he uses during his demonstrations.

Excel for Microsoft 365 is a subscription-based product that receives periodic feature updates. Conversely, perpetually licensed versions have year numbers in their names and do not receive any feature updates.
