Here is an interesting problem to start your day.

Let’s say you work as DNA sequencing engineer at The Enterprise. And you just unlocked the sequence that is responsible for all male problems. The early onset of baldness. The sequence code is AAAA. And you want to find out how many times this sequence is found in a sample of DNA strings, in the range B6:B19. Essentially you want the above.

So how do you write the formula?

Here is a quick & awesome way to make your dashboards sexy. Add an on / off switch to your conditional formats.

Take a look at above demo to understand what I mean.

Time for a quick personal update. We (Jo, kids & I) are moving to New Zealand on July 15th. We are going to Wellington and will be living there for next 2 years. New Zealand…Really? Why? How? To understand that, we need to go back in time, to EDATE(TODAY(), -75). In April 2010, I moved back to […]

My twins (Nishanth & Nakshtra) are now almost 7. They are super keen to learn how computers work. So the other day, I showed them Code.org where there are several coding exercises disguised as games. They loved those games … err coding exercises. So that got me thinking… why not make a game in Excel that teaches kids simple programming concepts.

So I built a Snowman & Hot Chocolate Maze game. In this post, let’s understand how to build such a game using Excel VBA.

Okay, this is an extension of the Neither “A” Nor “B” sum problem we discussed few days back.

Imagine you have a table named mydata with a few columns and a stop list named stop.list as shown above.

How would you calculate,

• Sum of Hours for all activities excluding those in stop list?
• Sum of all Regular hours for activities not in stop list?

So go ahead and post your answers in the comments.

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.
