Here is a familiar problem: You create a workbook to track some data. You ask your staff to fill up the data. Almost all the input data is fine, except the date column. Every one types dates in their own format. Here is a fun, simple & powerful way to warn your users when they […]

Learn two techniques to conditionally format the background of a chart based on some external value.

Today is Holi, the festival of colors in India. It is a fun festival where people smear each other with colors, water balloons, tomatoes and sometimes rotten eggs. This year we wanted to play with only water guns, but kids vetoed that idea vehemently. So we ended up driving to my sister-in-law’s place to play with colors (there were no rotten eggs or tomatoes, thankfully).

Let me smear a few colors on you

I would love to splash a jug full of color water on you and say Happy Holi. But the internets have not advanced thus far. So I am going to give you the next best option.

In the 31st session of Chandoo.org podcast, let’s disappear.

What is in this session?

Spreadsheets are complex things. They have outputs, calculation tabs, inputs, VBA code, from controls, charts, pivot tables and occasional picture of hello kitty. But when it comes to making a workbook production ready, you may want to hide away few things so it looks tidy.

That is our topic for this podcast session.

In this podcast, you will learn

• Quick announcements first anniversary of our podcast etc.
• Hiding cells, rows, columns & sheets
• Hiding chart data points
• On/off effect with form controls, conditional formatting
• Making objects, charts, pictures disappear
• Disabling grid-lines, formula bar & headings
• Hiding things in print

In the 30th session of Chandoo.org podcast, let’s learn how to uncover fraud in data.

What is in this session?

In the wake of hedge fund scams, accounting frauds and globalization, We, analysts are constantly second guessing every source of data. So how do you answer a simple question like, “am I being lied to?” while looking at a set of numbers your supplier has sent you.

That is our topic for this podcast session.

In this podcast, you will learn

• Quick announcements about 50 ways & 200k BRM
• Introduction to fraud detection
• 5 techniques for detecting fraud
  • Benford’s law
  • Auto correlation
  • Discontinuity at zero
  • Analysis of distribution
  • Learning systems & decision trees
• Implementing these techniques in Excel
• A word of caution

Who is the most consistent of all?

Imagine you are a category manager at a large e-commerce company. Your site offers various products, but you don’t really make these products. You list products made by other vendors on your site. Every day, these vendors would send you invoices for the amount of product they have sold. Above is a snapshot of such invoices.

Looking at this list, you have a few questions.

1. Who is the best seller?
2. Who is the most active seller?
3. Who is the most consistent seller?
4. Which seller has fewest invoices?

Let’s go ahead and answer these using Excel. Shall we?

Situation: Our commissions are growing way faster than revenues
Let’s say you are looking revenues & sales commissions of your company for last few years. The data looks like this:

And you want to highlight the fact that commissions are growing faster than revenues.

So you plot YoY growth rates for revenues & commissions.

Problem: The chart of YoY growth rates is not convincing

Take a look at the chart. It doesn’t convey the message that we want. At best it says “revenue growth is less than commission growth”

How to convey the message “Commission growth is a problem for us”?

Last week, I asked my email newsletter readers to submit “one data analysis problem you are struggling with”. We called it BYOD – Bring your own data. More than 100 people have emailed various interesting (and often very difficult) problems. This week (between 16th of February to 20th of February), let’s take a look at some of these problems and solve them.

Consolidating data in different shapes

We can use either VBA or Excel’s consolidation features to combine data that has same shape (ie same number & type of columns). Here is one way to do it.

But what if we need to consolidate data that is in different shapes?

Something like above.

In such cases, we can use 3 powerful tools.

1. Multiple Consolidation Ranges – Pivot Tables
2. VBA
3. Power Query

So let’s examine how to use these approaches to consolidate data in different shapes.

Imagine you are the in-charge of finance department at Hogwarts. So one fine day, while you are practicing the spells, Dumbledore walks in to your office and says, “Our electricity bills are way too high. As the muggles don’t accept wizard money, we have to find a way to reduce our power consumption.”

So you summoned the previous 12 month utility bills to examine energy consumption patterns, and pretty soon you realized that most of the electricity consumption is due to the light bulbs. You suddenly have a brilliant idea. Why not replace the light bulbs with a variety that consumes low power? A light bulb moment indeed.

Your next step is to figure out what varieties of light bulbs are out there. Fortunately this is easier than catching a snitch in a game of quidditch. A quick search revealed that there are 3 types of light bulbs:

• Regular incandescent bulbs (the kind Hogwarts currently uses)
• Compact Fluorescent Light bulbs (CFL)
• Light Emitting Diode bulbs (LED)

Now your job is to do a cost benefit analysis of these options and pick one.

Here is a common problem. Imagine you are looking a complex spreadsheet, aptly titled “Corporate Strategy 2020.xlsx” which as 17 tabs, umpteen formulas and unclean structure. Whoever designed it was in insane hurry. The workbook has formulas like this, =SUM(Budget!A2:A30, 3600)+7925 .

It was as if Homer Simpson created it while Peter Griffin oversaw the project.

So how do you go about detecting all cells containing formulas with hard-coded values?

We analysts like to compare. If you ever want to keep an analyst busy, just give her 2-3 options. She won’t return to your desk until the cows come home. My wife uses this trick all the time. Picture this:

[In late 2013]
Me: I want to buy a new phone
She: Do you want Nexus 5 or Galaxy S5 or iPhone 5s?

Its late 2014 and I am not done comparing.

So today, let’s talk about an interesting comparison scenario.

Comparing by letter or word

See above demo to understand the concept. Read more to learn how to do this.

This is a guest post by Sohail Anwar.

August 29, 1994. A day that changed my life forever. Football World Cup? Russia and China de-targeting nuclear weapons against each other? Anniversary of the Woodstock festival?

No, much bigger: Two Undertakers show up at WWE Summerslam for an epic battle. Needless to say: MIND() = BLOWN().

And thus begun one boy’s journey into understanding the phenomenon of Multiple Occurrences.

My journey continued, when just a few years later my grandfather handed me down a precious family heirloom: A few columns of meaningless data that I could take away and analyze in Excel. You may laugh but in the 90’s, every boy only wanted two things 1) Lists of pointless data and …

Today, lets talk about an interesting extension to the idea of in-cell charts. Adding average or target markers to the chart.

Adding a marker (like average or target or last year value) can enhance your charts greatly and provide more context. Lets understand how to add marker symbols to in-cell charts.
