The power of Pivot Table (Part I)

For the benefit of those who don't know what is pivot table and how it works, I will start from basic and progress gradually from simple to difficult.

What is pivot table and what it can do?
Pivot table is a tool that is provided in Microsoft Excel Application. It's purpose is to help you analyze the data you have. Pivot table in Microsoft Excel seems like a cheapo tool to many because it is just one of the features in Excel. What most people don't know is that it would have serve the needs of most data analysers. In fact, with the right experience, Microsoft Excel pivot table would have diminished the value of the crystal reports based on the price paid. Not only crystal report, but it can be a strong competitor for business objects, inpromptu and other reporting tools. I have used these other tools listed and I still fall in love with Microsoft Excel Pivot Table. It is easy to use and the amount time you need to learn how to use pivot table is much less than those reporting tools listed. What more, Microsoft Excel is a tool that is familiar to you and most probably, you have it on your computer.

The power of Pivot Table

I have spoken to many and am amazed that many Excel users are not aware of the existence of pivot table. For some, they have heard of it but have not used it before. To these 2 groups of people, I must say that they have not truly experience the power of Excel. In fact, my performance in data analysis improved by leaps and bounds after I learnt about Excel's pivot table.

For those who have used Excel Worksheet as a data source, you are one step ahead of these two groups. But you are only using 30% of Excel's pivot table capability. Those who are already using MS Query would have harness the true power of Excel pivot table. In fact, it would take about a day for me to cover every aspects of Excel's pivot table. In the next few days, I would share with you some of these functions so that you could appreciate what Excel pivot tables can do for you and how it could improve your data analysis capability.

Getting the list of unique records (Method 1)

Previously, we touched on the various methods to count the number of unique records listed in an excel worksheet. However, nothing was mentioned about producing the list of unique records using Excel. And I thought you might be interested to find out how. And here is one method you could use:

Assuming that the following product list is in column A starting in row 2.

What is a blog
Internet Marketing
Excel Formula
Adword Equaliser

Adword Equaliser
Excel Formula

1) Sort the list so that all the same items are group together.
2) In cell A2, input the formula "=if (A2=A1,1,0)".
3) This formula will check to see if the cell A2 is the same as A1. If they are the same, the number 1 will appear. If they are different, the number 0 will appear. Since we have grouped the same items together, the 1 will appear if item appears the second or third time in the list. For example:

Adword Equaliser 0
Adword Equaliser 1
Excel Formula 0
Excel Formula 1
Excel Formula 1
Internet Marketing 0
Internet Marketing 1

What is a blog 0
4) Activate the autofilter function and filter using the criteria "0"
5) Once the duplicates are hidden, use the Goto Special function to extract the unique list to another excel worksheet.
Mission completed.

Press the F5 function key and then click on the Special button. Select the option "Visible Cells only" (see diagram). Click "OK". Only the visible cells are selected for now. Activate the copy function, go to another Excel worksheet, select a cell say A1 and activate the paste function.
