Filtering is one of the most used feature in Excel. It is a quick way to take lots of data and narrow down to the subset we want.
But here is one common filtering scenario that is slow as snail.
Imagine you are looking at some sort of sales data (if you can’t imagine, look at the above demo).
Now, you want to filter this list for gender=male, profession=self-employed, product category = chocolates and quantity = 1.
If you use the right click, filter > filter by selected value approach, this will take several clicks.
Wouldn’t it be cool if you can select the entire combination and say filter?
Unfortunately, no such feature exists in Excel.
But you are not aiming to be ordinary in Excel. You are aiming to be awesome in Excel. That means, you don’t take no for answer.
Fortunately, we can quickly write a VBA macro that filters a list by selection. So let’s do that.Continue »
Recently, we discussed about the case of unwieldy data and how we lookup what we want using formulas like SUMIFS. Today, let us learn few more ways to solve the same problem.
Suitable structure spawns simple solutions
Poorly structured is the 2nd biggest problem of analysts. The first one is not enough coffee. That is why there is a dictum in the data analytics world.
Structure is everything
So, we can easily solve our lookup problem, if our data were to magically re-arranged in 2 column fashion – Data & Value.Continue »

In part 4 of our VBA Crash Course, we are going to create our very first VBA application using what we learned so far.
We will take the “We Are Nuts” example and create a daily sales tracker application using all the things you have learned so far. You can download the example VBA workbook and play with it to learn better.Continue »
In part 2 of our VBA Crash Course, we are going to learn what Variables, Conditions & Loops are and how to use them in Excel VBA.
What are Variables, Conditions & Loops?
If you are new to computer programming, you might think I am speaking legalese. So, to make it easy to understand, lets assume you run a bunch of stores across the town. To make it colorful, lets call your stores “We are nuts” – a dry fruit and nuts store chain. At the end of every day, you call each of the 24 store managers and ask them how much sales they have made in that day.
Now, you are not the kind of boss who micro-manages & nitpicks. So you don’t really note down sale for every store. Instead, as you call the store manager, you just mentally update the total. So first store says “$2,300” your total is 2300. Second manger says “$4,000”, the total now will be 6300. So on.
The value 6300 here is nothing but a variable.
We will use the “We are nuts” example thru out this lesson & towards the end we will build a sales logging application using Excel VBA.Continue »
