Pivot tables are perfect for summarizing a large amount of data -- they roll thousands of records into a single line, and show the total amounts. Occasionally, you might see duplicates in a pivot table, instead of a single summarized item, like the Boston amounts shown below.
Usually, this is caused by extra spaces at the end of an item, and you can clean up these trailing spaces to fix the problem.

To prevent duplicate entries in an Excel column, you can use data validation, with a custom formula. In this example, employee data is being entered, and each employee must have a unique ID number.
With data validation, using the COUNTIF function, a warning will appear if a duplicate number is entered. This video shows you the steps for creating a formatted table, naming one of the columns, and setting up the data validation.

Here are a few more Excel articles that I read this week, that you might find useful:
If you don't want people to see a worksheet, you can right-click on its sheet tab, and click Hide. This isn't a security feature though -- it's just as easy to unhide a sheet! If you want to make it a little tougher to see a sheet, you can change its properties to make it Very Hidden. This video shows you the steps, and you can read the details in this blog article.
It's almost fall, here in Canada, and our garden is full of ripe tomatoes. It's full of weeds too, but we won't talk about that! ;-) I usually make tomato sauce, and store some in the freezer, so we can enjoy the garden crop in the winter months too.
