## Avoid Hiring Boo-boos with Excel – COUNTIFS for the win [video]

Published on Apr 26, 2017 in Excel Howtos, Learn Excel

Imagine you are head of human resources at Casual Contracting Co. Every month you hire a lot of temporary staff who spend 1-4 months with CCC before leaving. Sometimes you hire the same people again. Of late, you have noticed a strange process gap. You are paying same person two (or more) salaries.

This is because you are hiring a person for new temp role even before their current one ended. See above picture.

So how to avoid making such hiring boo-boos.

Simple, using Excel of course.

Published on Apr 21, 2017 in Excel Howtos, Learn Excel

While tables are super helpful, they do come with some limitations. Today let’s examine one such unique problem and learn about an elegant solution.

Imagine you run an office furniture company. You want to stop reordering two brands of furniture – Relaxer (a type of chair) and Boca Top (a type of table). You currently have 20,000 Relaxer chairs and 5,000 Boca Tops. These are valued at \$200,000 and \$100,000 respectively. When sold, they will yield \$100,000 and \$25,000 gross profit. You are hoping to sell them off in 2 or 3 years. You forecast that we can sell off these as per some yearly schedule.

## How many employees are on leave during Easter holidays [Homework]

Published on Apr 7, 2017 in Excel Challenges

Easter is around the corner. After what seemed like weeks of lousy weather, finally the sun shone today. I capitalized on the day by skipping work, walking kids to school, taking Jo out for some shopping, enjoying a leisurely walk / cycling with Nishanth in the park and almost forgetting about the blog. But it is dark now and before tucking the kids in, let me post a short but interesting home work problem.

Let’s say you are HR manager at Egg Co. and you are looking at the vacation plans of your team.

Easter is your busiest time and it would be a bummer if a majority of your staff are on leave during the Easter season (14th of April to 28th of April, 2017). So you want to know how many people are on leave. A snapshot of your data (table name: lvs) is shown above.

You want to answer below three questions:

1. How many employees are on leave during Easter holidays (14th of April to 28th of April)?
2. How many employees are on approved vacation during Easter holidays?
3. How many employees in “Team ninja” are on approved leave during Easter holidays? Assume team employee numbers are in named range ninja

## Hide columns one one tab same way as they were in another place [quick tip]

Published on Apr 5, 2017 in Excel Howtos

One of the regular reporting tasks I do involves a manual step I hated. It goes like this:

• Dump several columns of data in the template file.
• Hide a particular set of columns (these are not together, so must be done one at a time or with CTRL+selection)
• Save and publish the file.

After doing this manually for last few fortnights, today I wanted to automate the column hide process. I was about to write a VBA macro to clone the hide settings from one workbook to another. But then I thought, may be paste special can be of use.

And what do you know. It does exactly that.

Published on Apr 3, 2017 in Charts and Graphs, VBA Macros

Few days ago, I saw a beautiful homemade science experiment on Sand Pendulums on Bruce Yeany‘s YouTube channel. Go ahead and check it out. It is a cool project to do with your kids.

I will try this experiment with kids during school term holidays around Easter. But first, I wanted to try the simulation in Excel.
