Clean data quickly with Flash Fill

Clean data quickly with Flash Fill

Excel has many powerful & time-saving features. Even by Excel’s standard, Flash Fill is magical. Introduced in 2013, Flash Fill is a rule engine to Excel’s fill logic. Every time you type something in a cell, Excel will try to guess the pattern and offers to fill up the rest of cells for you. That is some serious time saving magic.

Let’s understand what Flash Fill is and few sample use cases.

We all know that area charts are great for understanding how a list of values have changed over time. Today, let’s learn how to create an area chart that shows different colors for upward & downward movements.

The inspiration for this came from a recent chart published in Wall Street Journal about Chinese stock markets.

We will try to create a similar chart using Excel. We are going to create the above chart in Excel.

How to find out if a text contains question? [Excel formulas]

How to find out if a text contains question? [Excel formulas]

On Wednesday (15th July), I ran my first ever webinar, on a topic called, “How to be a BETTER Analyst?” (here is the replay link, in case you missed it).  It was a huge success. More than 1,100 people attend the live webinar and hundreds more watched the replay. As part of the webinar, we had interactive Q&A. Viewers posted their questions and I replied to as many of them as I can.

After the webinar, I wanted to make sure I covered all the questions. So I downloaded the chat history. There were more than 700 messages in it. And I am not in the mood to read line by line to find-out the questions. A good portion of chat messages were not questions but stuff like ‘hello everyone, I am from Idaho’, ‘Wow, Chandoo has beard!”, “Enjoying a beer in Belgium while watching webinar” etc. So I wanted a quick way to flag the messages as question or not.

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

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.
