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

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.

Relative References in Excel Tables

Excel Tables have been around for a decade now (they are introduced in Excel 2007), and yet, very few people use them. They are versatile, easy and elegant. At Chandoo.org, we celebrate Tables all the time. If you have never used them, start with below tuts.

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.

Reshaping your data easily – Case study [Pivot tables FTW]

Reshaping your data easily – Case study [Pivot tables FTW]

Late. Jayaram, my uncle is also a teacher. When I was a kid, I used to spend a lot of time with him, learning all sorts of things. He taught me chess, maths and so many life lessons. I remember one such lesson very vividly.  One day, he asked me to do something. I did it in a very long way. After seeing me struggle for several minutes, he chipped in and showed me how to do it easily. He then said, “when someone asks you where your nose is, you don’t twist arm around your head. You just point to your nose directly.”

The idea is that when you have a direct, simple way to do something, you should use it.

Nose and pivot tables… how are they connected?

We are coming to the point. Read on for full case study and solution.

Untrimmable Spaces – Excel Formula

Published on Jan 12, 2017 in Excel Howtos, Learn Excel
Untrimmable Spaces – Excel Formula

Let’s talk about the untrimmable spaces.

We all know that TRIM() removes extra spaces from the beginning, ending and middle of a text.

So for example, if A1 has ” something and    one   more    ”

TRIM(A1)

will give “something and one more”

We can use CLEAN() function to remove non-printable characters (like the ASCII codes 0 to 31).  Of course, SPACE is technically a printable character, so CLEAN() won’t remove spaces.

The untrimmable spaces…?

The other day Sreekanth emailed me a sample of data and asked, “how do I remove the spaces in this list and convert them to numbers?”

Naturally I tried to TRIM().

But the data won’t budge. See above.

Hmm, let’s investigate why.

Finding the closest school [formula vs. pivot table approach]

First a quick personal update: There has been a magnitude 7.8 earth quake in NZ on 14th November 2016 early morning. It is centered in Kaikoura, which is about 250 km away from Wellington. We did feel several shakes and after shocks. It has been an interesting and often scary experience. But my family is safe. I feel very sad for the all the damage and the loss for families in NZ. If you suffered from this quake, My prayers and thoughts are with you.

Yesterday, a friend asked me an interesting question. He has school distance data, like above. He wants to know which is the closest school for each school.

There are a few ways to answer this question. Let’s examine two approaches – formulas & pivot tables and see the merits of both.

Finding if a cell has 7 in it… [Pattern matching in Excel]

Imagine you work at MI5 as a HR officer. You want to find all agents who have license to kill (licence 7). Your data looks like above.

How would you go about it? 

If you filter the list or use FIND() or SEARCH() formulas, you will end up with agents who also have licenses 77, 17 or not7. So how would you solve this problem?

Of course, you do what any smart person does. You summon Excel and ask it nicely by using some wicked pattern matching logic.

Check if a range has all numbers from 1 to n [Homework]

Check if a range has all numbers from 1 to n [Homework]

Finally, spring weather showed up in Wellington this week. We cashed it as much as possible by going on treks, cycling trips, more treks and of course doing laundry.

Anyways, I don’t have time to blog. I must go out and help kids with some cycling. But I want to keep you busy this weekend. So here is a fun homework problem.

Does my range have all numbers from 1 to n?

Let’s say you have a range called range (duh!).  And you want to check if range has all the numbers 1 to n (say n=5) in it, each number appearing only once (no more, no less). You can assume the named ranges range and in your formulas.

See above examples to understand the problem.

So go ahead and post your formulas in the comments section. I will sneak in whenever I can to look at all your creative answers.

Surprisingly, each formula gives a different result! So which one should you use?

So how do you write the formula?
