Description:

Excel expert David Ringstrom, CPA, teaches you how to identify and manage duplicate data within your spreadsheets in this live presentation. Topics he covers include: 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, such as SUMIF or COUNTIF, to sum or count instances of duplicates. David also explains how to use the MATCH worksheet function to identify differences in two separate lists, how VLOOKUP stops searching for duplicates after an initial match is found, and how to use the Data Validation feature to ensure users can’t enter the same data more than once in a given area of a spreadsheet.

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.

  • Using the Reapply command to remove items that are no longer duplicated within a list.
