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.

Let’s Celebrate Clean Data and 1000 Subscribers!

Thanks to everyone who’s subscribed, commented, sent in questions that became videos. Around this time last year I changed my video production style and you’ve responded surprisingly well.

This channel is about to cross the 1000-subscriber mark. What should we do about that? I would like your suggestions for a video that I can make for you. Let’s make something fun and unusual!

At this moment we’re 27 subscribers away. So, we’ve got a little time to put our heads together and explore ideas.
