Like the other applications in Microsoft Office 2007, Excel 2007 boasts upgraded features and a brand-new look. In Excel 2007 Essential Training , instructor Lorna A. Daly introduces the new version in detail. The training begins with the essentials of using the program, including how and why to use a spreadsheet, how to set up and modify worksheets, and how to import and export data. Lorna then moves on to teach more advanced features, such as working with functions and macros. Exercise files accompany the tutorials.
How often have you spent hours looking through lists of data looking for duplicates. Just to make sure that the information that you're working with is clean as clean can be. Well, no need to do that any longer. Now we have a command called remove duplicates that will allow you to do this very, very quickly. Open up the worksheet for StoreA to follow along. First thing you want to do is you want make sure you're looking at the Data tab, because that's where the Remove Duplicates commande is sitting. Once you've gotten there, the next thing you want to make sure is that you've selected your whole table to work with. And how do you know you've got your whole table? Well if you scroll through this particular worksheet, and you come down to the rows 25, 26 and 27; you'll notice a couple of things. Visually, you'll notice that you're shading--your mixed shading--has stopped.
Row 26 should be shaded a little bit as should row 28, but it seems to have stopped there. So if I was to select my table and go to Remove Duplicates right now, it would stop right at this particular point, because that's not part of the table. Another way I can tell is there's a tiny little tag right in cell E25 that indicates that I've stopped my table right here. I just simply need to select that tag, pull it down, and notice how I'm now expanding the selection grid to include the last few lines. Visually, you can tell you've included those extra lines in your table, because now you have the shading available for you.
Let's see that one more time. Go back up to your Quick Access toolbar and do Undo Table Resize. Make sure you find the cell that's got the little tag in it, and you'll notice that it's right at the very bottom right-hand corner of the final cell in your table. Move your mouse until it changes into a double headed arrow, and click and drag to expand and resize your table. You've included the extra rows into your table because you've got some shading going on. That's how easy it is to resize your table. And that's very important When you want to remove duplicates. Now we're ready to go and remove the duplicates. So we'll go back up to our very first cell, and we can do that by going over to our name box over here and typing in A1 and hitting our Enter key, and it pops us right up to the very top of our screen.
So that's an easy way to get through your tables from the bottom of your rows up to the very beginning of your spreadsheet. Alright, so, I'm now in cell A3 to make sure that I'm actually active in the table itself rather than just on the title bars, and I go over to Remove Duplicates. So Remove Duplicates command deletes duplicate rows from a sheet. Now, it's very important that you understand what you doing when you're removing duplicates. When you're removing them, it is actually removing the information itself and there's no Undo once you remove the information. Once it's gone, it has been deleted. It's gone.
The other thing that's important to realize about removing duplicates is it has to be a match on every single cell within the row. If I had a different Item Type, if I was using an abbreviation for Vanilla, it would not match it. It's not that smart. We're ready to remove our duplicates now. We go up to the command, we click on the button, and it asks us to identify what column do we want to check for duplicate values on. Well, in this case, I can select all the different columns in my worksheet, or, I could just look for duplicates on Item Type.
So I select that, I click OK. It tells me it found 7 duplicate items and it removed them, and it left 20 unique values. There's my new list. so now I only have one item for Chocolate, Vanilla, Marble, Pastry, and it's removed any other duplicate item that I have here. Pretty slick isn't it? And saves you hours and hours of time.
