SUMPRODUCT Vs. Power Query on Mt. KauKau

SUMPRODUCT Vs. Power Query on Mt. KauKau

When faced with tough problems I react in one of three ways

  1. Come up with ingenious solutions
  2. See if a simpler cheat solution is possible
  3. Sit back and ignore

For most problems, I choose 3rd reaction. Occasionally, I rely on 2nd option and very rarely the first one.

When faced with a tricky time sheet summary problem (as outlined above), after initial lethargy I wanted to solve it.

Avoid Hiring Boo-boos with Excel – COUNTIFS for the win [video]

Imagine you are head of human resources at Casual Contracting Co. Every month you hire a lot of temporary staff who spend 1-4 months with CCC before leaving. Sometimes you hire the same people again. Of late, you have noticed a strange process gap. You are paying same person two (or more) salaries.

This is because you are hiring a person for new temp role even before their current one ended. See above picture.

So how to avoid making such hiring boo-boos.

Simple, using Excel of course.

Figuring out Employee Churn with Power Query [HR Analytics]

Let’s say you are the people manager at ACME Inc. You are looking staff list for the months – January and February 2017. You see that we had 4,000 employees in Jan and 4,200 employees in Feb. So what is the churn?

  • Is it just 200?
  • Or is it the sum of people who left and who joined?
  • What if you want to find out how many people moved to new designations / departments or groups?

You see, churn is tricky to figure out.

So why not invite the pros? ie Power Query.

Decorate your TPS reports with spooky spider web chart [Halloween Fun]

It’s Halloween time. As adults, we can’t go trick or treating. We can of course dress up in costumes and entertain others. But what about the poor spreadsheets. Don’t they deserve some of this fun too?

Hell yeah! So I made a spider web generator in Excel. Just use it to make a spooky cob web pattern and add it to your report / dashboard / time sheet or whatever else. Surprise your colleagues.

A quick tip about data analysis while on bike [Video + Personal]

Wellington(NZ) sure is beautiful on a clear day. There are so many cool bike tracks, walking trails and beaches to keep you busy. Today, I went cycling on my usual route towards Makara beach. At the turn off point, I thought, “This is selfish. I can’t keep all this beauty to myself. I must share it with you.” So here we go.

A quick video about data analysis while on bike

Technically, I was not on bike when recording this video.  Watch it below or on our YouTube Channel.

Mapping Spread of Obesity [Chart Critique and Alternatives]

Mapping Spread of Obesity [Chart Critique and Alternatives]

Over at Flowing Data, Nathan has published an interesting visualization about spread of obesity.

While the above chart is quite interesting, it doesn’t offer much insight in to the data. There are a few drawbacks,

  • Understanding obesity trends for a given state over the years is hard due to the layout and format of the chart.
  • Finding which states are experiencing most obesity growth rates is not possible
  • Ironically, the chart itself is obese. It takes too much space to explain the data.

Nevertheless, the chart looks cool and can be reused with smaller data-sets (quarterly trends or just for a few years). So let’s recreate the same in Excel. While we are at it, let’s also build an alternative visualization to explore the obesity data.

Sara’s Copy Shop – Break even analysis and what-if modeling in Excel [Videos]

Last week, I asked you to share an analysis problem that you couldn’t solve in Excel. We got quite a few very interesting problems in comments and email. In this post, let me explain how to solve Sara’s copy shop problem using Excel.

What is Sara’s copy shop problem?
Thanks to Caroline who posted this problem.

Sara wants to open a copy shop. Each copier costs $5,000 per year to lease. The rent & other fixed costs per month are $300. There is a $0.02 variable cost per copy. Each copier can print up to 100,000 copies per year. She plans to charge $0.11 per copy from her customers. Sara estimates that the demand can be any of the 4 values – 500, 1000, 1500 or 2000 copies per day.

  1. Build a model to estimate profit per given number of copiers & demand values
  2. Find the mix of copiers & demand values that can make maximum profit for Sara (copiers – 1 to 6, demand – 500 to 2000)

Sum up neither “A” nor “B” values – How to use DSUM function in Excel [video]

We know how to use SUMIFS function to answer questions like, “What is the sum of values for ‘A’?”  But how would you answer questions like,

  • What is the sum of values that are neither “A” nor “B”?

We can still use SUMIFS, but it will get awfully long. So let’s turn our attention to other functions in Excel.

Earth Venus cosmic dance – Animated chart in Excel

Recently I saw an interesting Earth Venus cosmic dance video on Facebook. See the original video below or here.

Although this is not entirely accurate from physics & astronomy perspectives, the dance is a stunning example of patterns that are generated by simple things.

I wanted to recreate this cosmic dance in Excel. How else am I to get my spreadsheet fix on a Saturday?

Here is a quick demo of the final outcome. Read on to learn more about the Earth Venus cosmic dance.

Tell all versions of truth [Dashboard Best Practice]

Here is a simple but effective rule for your next dashboard. Tell all versions of truth. All versions? But there is only one version no? Of course, there is only one version of truth (or data), but you can present that in different ways, thus creating different perspectives, offering different insights. By using an interactive element (slicers […]

A slicer that doesn’t slice [Pivot Table Tricks]

A slicer that doesn’t slice [Pivot Table Tricks]

Mary Ellen, one of our readers, has an interesting conundrum,

I have some data that goes to Pivot table then to pivot chart. There is a slicer to filter the data. But when I slice, my pivot chart gets messed up. How to have the slicer, but still see the insights in the chart?!?

See above demo to understand:

This is because when you slice by a school, the pivot table gets filtered and hence % row total for that school becomes 100% (as there are no other schools).

How to fix the problem? The easy answer is to remove the slicers. But we want to have our slicers and eat a slice of them too. So we crank up the Excel awesomeness valve and get to work. There are two ways to achieve what we want.

  • Old school method: Two pivot tables, some formulas & a line chart
  • New Excel method: Power Pivot and a line chart
