Quickly filter a table by combination of selected cell values using VBA

Published on Jul 15, 2015 in VBA Macros
Quickly filter a table by combination of selected cell values using VBA

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.

Celebrate Holi with this colorful Excel file

Celebrate Holi with this colorful Excel file

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.

How to consolidate data that is different shapes [BYOD]

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.

How to check for hard-coded values in Excel formulas?

How to check for hard-coded values in Excel formulas?

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?

Compare 2 sets of data by letter or word & highlight mismatches [vba]

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.

Looking up when data won’t play nice – few more alternatives

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.

To all our readers & friends from USA,

I wish you a happy, fun & safe 4th of July.

For the last 4th of July (2013), we (Jo, kids & I) were in USA. We went to Washington DC to meet up a few friends for that weekend. And we had one of the most memorable evenings of our lives when we went to national mall area in the evening to watch beautifully choreographed fireworks. Kids really loved the amazing display of fire-crackers and enthusiasm.

While we all are back in India this time, it doesn’t mean we cant celebrate 4th of July. So I made some fireworks. In Excel of course.

Here is a little Excel animation I made for all of us.
