Join Dennis Taylor for an in-depth discussion in this video Identify data that's been duplicated using a specialized array formula, part of Excel 2011 for the Mac: Managing and Analyzing Data.
- In this workbook, we're looking at a worksheet…called "Identifying Duplicates."…In an earlier movie, you might have seen…how to remove duplicates from a worksheet.…On the other hand, sometimes it's just as important…to identify which records within a list…have been duplicated.…For example, in rows 4 and 5,…we do see…the information on Juan Bishop has been duplicated.…In this situation, we must make sure…that the duplicates are together.…Usually, they will come together simply by sorting.…Let's show two different ways to identify these duplicates.…
In both cases, we'll begin by inserting…a new column to the left of column A.…Simply right-click column A and Insert.…I'll zoom in a bit…using control shift and the mouse wheel.…You can also this with control shift…and two fingers on a trackpad…or control shift and a single finger on a magic mouse.…All right, we're going to write a formula here…comparing,…for example,…the data in rows two and three,…and then we'll copy it down the column.…And we can use the countif function.…
