The Wildest Excel Spreadsheet Ever: HLOOKUP and the Importance of Building a Model

NOTE: This video isn’t about the details. It’s the thought process. So, please don’t worry if you don’t catch everything.

Subscriber, eCabinets Tips and Tricks asked about the most bizarre spreadsheet I’ve ever faced, and what I did to untangle it.

‘Bizarre’ can be measured a lot of ways. I chose this example because it almost beat me. I almost threw up my hands and accepted defeat. It was too big to even try to handle manually.

I’ve faced spreadsheets that had far more complexity, but I could see the solution and it was just a matter of plowing through. But this one … it took a week to find a way to even get started.

It was a spreadsheet that had 2000 rows and over 600 columns. The data in the columns were all out of order, and needed to be moved in groups of 15. My job was to get them all in order.

Two things made a solution possible:
1. HLOOKUP (this is the only time I’ve ever used HLOOKUP. Ever.)
2. Making a small, simple model of the problem that could then be scaled out to the real data.

#2 is what I really want to stress: when a task is overwhelming, slow down. Make a small model. Clear away the noise and just focus on developing a solution.

Excel Power Query: Clear Line-Breaks (A correction to the previous video)

Here’s a quick video correcting 2 things from the previous video: Import Data from Web Page and Clear Line-Breaks

Thanks: Wyn Hopkins, Micheal Reynolds and Chris Pope for pointing these out:
1. There was a single carat delimiter that I missed
2. There’s a way in Power Query (Get and Transform) to separate columns by line-feeds and carriage returns.

Have a look! And thanks for being in the battle against Crap Data.

Also, I mention the Amsterdam MVP Excel Summit. It’s 2 days of Excel MVPS teaching the public the greatest about Excel.
It’s 18 and 19 April. Here’s a link for more details:

Excel Power Query: Import Data from Web Page and Clear Line-Breaks

Power Query has Clean and Trim features, but sometimes those don’t work with line-breaks.

1:49 Importing the data from the Wikipedia page
2:29 Unpivot
3:13 Split columns
3:35 Explanation of the problem of the data being on multiple lines
4:30 Clean & Trim (they don’t work)
4:48 Setting up the data to
5:36 #(lf) to expose the line-feeds
6:22 Split columns
6:50 Unpivot

This video imports data from a Wikipedia page and cleanses it. The problem is each cell has a tall column of data that needs to be parsed. To do this, watch how we have to get crafty because it’s necessary to handle this with M code.

We have to use #(lf)

Along the way, you’ll see:
Unpivot,
Replace Values
Trim and Cleanse
And lots of fire.

Power Query Merging Columns and M Code (managing nulls and excess delimiters)

In this video, I go deeper into the issue of clearing excessive delimiters after merging columns in Power Query (Get and Transform).

The previous, related video:

This video describes:
1. Why my hack worked.
I replaced nulls with: ^
Then systematically replaced the ^ symbols. This is much better that merging columns and having lots of delimiters stuck together

2. An M-code solution that Owen Auger helped me with, using
List.RemoveNulls
This is a single step and very clean. However, this solution is in the world of writing code and is great for those who are comfortable with coding.

Check out the previous video to see how this can be handled in native Excel by using the TEXTJOIN function.

Also mentioned in the video; other giants in the world of writing M-code:

Power Query Merge Columns

More about working with Excel’s Get & Transform (aka Power Query). this time, we explore merging columns and the “gotchas” that you need to know about.

0:49 Description of the 3 warnings
1:09 Showing the problem
2:00 Problem 1: The source columns are gone
2:17 Problem 2: The columns are out of order
2:50 Merge properly
3:09 Problem 3: Excess delimiters
3:29 A hack for replacing the excess delimiters
5:12 Using TEXTJOIN to do the work in native Excel

The problems:
1. The source columns disappear after you merge. If you need the source columns to do other calculations or transformations, you’ll need to duplicate those columns, then merge the duplicates.

2. The final order after merging depends on the order that you highlighted the columns. In this video, I highlighted column 3 first, and then 1, 2 and 4. Yup! The data merged out of order.

3. If you have blank cells, Power Query will add a delimiter any way. And those delimiters are tricky to get rid of! I show you a hack on how to clean those out.

To compare, I show you how to do the same thing in native Excel by using TEXTJOIN

Complex IF Formula Converted to 2-Way Lookup with INDEX-MATCH-MATCH

0:00 – what we’re up to
1:21 – looking at the problem
5:12 – a word “going rogue” as an effective style
6:09 – starting the solution
6:29 – using RANDBETWEEN to make up some data
7:14 – making dropdown lists
8:07 – INDEX-MATCH-MATCH making the 2-way lookup
10:00 – summary and final comments

Someone sent me a spreadsheet that had a large complex formula in it. There were 5 IF statements inside each other and some CHOOSE functions.

**NOTE: this video moves fast because the concepts are more important than the how-to.**

This video focuses on the thought process of:
– understanding the formula and user’s needs
– realizing that the formula is using 2 variables to retrieve a piece of data
– the objective is really a 2-way lookup
– INDEX-MATCH-MATCH is what we’ll use to get Excel to retrieve the data.

Another important point is that I don’t try to recreate the person’s data inside the original spreadsheet. I focus on the concept and getting the 2-way lookup working.

This way, it’s not necessary to try to understand the person’s business, terminology, and all the details of how they developed their spreadsheet. Full attention can be devoted to getting the 2-way lookup working. Then, hand it back to the user and let him recreate the mechanism as he needs it.

One thing to appreciate is that the user wrote an effective formula with the IF and CHOOSE functions. This video just shows a cleaner alternative.

Referencing Queries with Get & Transform: Segmenting, Cleaning and Appending a Messy Dataset

“Reference a Query” is a feature in Excel’s Get and Transform, and it’s not obvious what it does. From the outside it looks the same as Duplicate Query.

This video shows an example of when you’d reference a query and how the feature is used.

Here, we received a dataset that looks like 2 datasets that had been stuck together. They need to be separated, cleansed 2 different ways and then put back together.

“Referencing the Query” allows the user to segment and cleanse the data while remaining connected to the source data in case updates are made.

Celebrating 1000 Subscribers to Excel on Fire

Thanks for all of the suggestions on what we could do with this CELEBRATION OF 1000 SUBSCRIBERS!

In this video I responded to your suggestions and there’s no Excel here. Surprisingly, more people were interested in “a day in the life.” So, you get a bit of that–including a recipe for cooking alligator.

I hope you enjoy the video! Be in touch, and please comment.
