Today, lets talk about Power Pivot & understand it.
What is Power Pivot?
Power Pivot is an Excel add-in to connect, analyze & visualize massive amounts of data.
Lets take a closer look at the definition.
Connect: You can use multiple tables of data & set up relationships between them using Power Pivot. For example, you can connect customer details to sales transactions so that you can summarize sales by customer location or gender easily.
Analyze: You can create simple pivot table style reports or create something exceedingly complex by defining your own calculated fields for values area of the pivot. There is a whole set of formulas defined for exactly this purpose, called as DAX formulas.
Visualize: Instantly filter your reports using slicers, time lines (Excel 2013 or above only), conditional formats, pivot charts etc. You can even define KPIs and see the performance in bands.
Massive Amounts of Data: Although your typical Excel worksheet contains a million rows, if you tried to load even half of those with any data, Excel would quickly become slow & lazy. Power Pivot can take a million rows for breakfast and would be hungry for more. It can processes millions of rows of data very quickly and easily, all from the comfort of a standard desktop or laptop.
Excel Add-in: Power Pivot is an optional free add-in that works with Excel 2010 or above. If you are running Excel 2010, you need to download and install it. Users of Excel 2013 have it easy. Power Pivot comes pre-packaged with Excel, you just need to enable it.
A brief introduction of Power Pivot
It would not be an understatement to say Power Pivot is the most awesome data analysis feature you will ever come across in Microsoft Excel. Since you would not take something short of awesome for this introduction, I recorded a 25 minute video explaining what Power Pivot really is and how it works. Watch it below:

Looks interesting, what else can it do?
The video just scratches the surface of Power Pivot. You can do so much more by using & mixing various features of Excel & Power Pivot. Few possibilities are,
- Define your own measures (calculated fields for power pivot reports) that can summarize data the way you want
- Sum of sales YTD
- Count of distinct customers per product
- Ratio of sales made to single moms vs. single dads
- % of products made by top 10 employees in all etc.
- Slice and dice data anyway you want
- Filter all reports & charts based on multiple linked slicers
- Slice reports based on values in another (non) related table
- Fetch data from different data sources & integrate
- Set up Power View sheets to create rich visualizations of your data (Excel 2013 only)
- Create maps, rich interactive charts & more
- Integrate with Excel features to create stunning reports & dashboards
- Combine Power Pivot outputs with Excel features like sparklines, conditional formats, charts & form controls
- Use references to fetch pivot table values & present them in dashboards
and so much more.

Do you use Power Pivot?
I first heard about Power Pivot in 2010, But I did not learn it then. Since October, last year, I have started learning and using Power Pivot and have been in love with it ever since. I think it is really powerful and capable. As I am learning new things about it, I am very eager to share them with you on this blog & thru our upcoming course.
What about you? Are you using Power Pivot? What is your experience like? Please share using comments.

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
