Excel 2007: Highlight Duplicates
Using conditional formatting, you can easily highlight duplicate values in your spreadsheet. This will make it easier to identify the duplicates so that you can remove them. To do this…
1. Select the column that is to be checked for duplicate values.
2. Go to the Ribbon and select the Home tab.
3. In the Styles section, click Conditional Formatting.
4. Select Highlight Cells Rules and click Duplicate Values.
5. In the Duplicate Values dialog box, choose the formatting you wish to use from the dropdown. The default is a light red fill with dark red text.
6. Click OK.
The background color of all values that appear more than once in the selected column will show the selected formatting.

This is great for identifying duplicates in individual columns, but how about an exact match with multiple columns?

For multiple columns, try to find duplicates using the same formula after concatenating the values of the columns into a separate column

UGG Highkoo Boots said on December 7, 2010
This year we really have been spoiled as UGG Gissella Boots have brought out 17 new designs of boot for the womens collection! All of which are very classy without compromising in comfort. Cheap UGG Boots are successful based on these 2 points, and once you have experienced walking in you will never turn away from them. In fact there are lots of women who can’t wait for winter because it means that they get to wear them again! See in more detail the new boots!
UGG Upside Boots is approached as the perfect boots prevent snow and rain. As kind of UGG Roxy Tall Boots are a sleeker that have more tightly designed UGG Bailey Button Boots with great features like a Vibram outsole,a waterproof Leather upper and a fully-lined fleece sockliner.What’s more UGG Classic Tall Boots removable sheepskin sockliner provides extra warmth and comfort.
I love my UGG Boots! I decided this particular style, because each one has its original style. I like UGG Highkoo Boots being different. I wear them with boot cut Levi’s jeans and they look great. Even led them to a night club and received many compliments. They are very fashionable, if you live in New York UGG Sundance II Boots. They are very comfortable and warm as well UGG Mayfaire boots. 90% of the time used without socks. I wear a size 8 1 / 2, but I bought a size 8, because they run a little big. Worth the money and I can say that doing well in snow. Thanks to Ugg Nightfall Boots and UGGS!
