An Excel Meditation with Tables, XLOOKUP, Dynamic Arrays in a Dynamic Dropdown List Solution

During the Azerbaijan Power Bi & Modern Excel Meet-up last week, Faraz Shaikh presented and shared a lot of cool Excel tips. There was one tip that stood out for me: Extracting a table’s headers into a Dynamic Array. 😲 It was amazing! It got me thinking about how this could be applied.

In this video I show how to create a dynamic dropdown list that uses the table headers to extract specific data.
You’ll see: XLOOKUP, SORT, FILTER, TRANSPOSE in this solution.

Excel Hash 2021: The Facilitator | LET function | Power Query Custom Data Types | Excel Challenge

0:00 Introduction
1:06 My Solution
5:13 Rabbit needs water
7:26 Correction with the EVEN function

ExcelHash is back for 2021! This year we added more participants. Check out the full playlist and think about how you would create a solution.

The premise:
Take 4 random Excel features and bring them together into an integrated solution. It’s pretty difficult and forces a person to justify their choices; thinking about the essence of a feature.

ExcelHash 2021 Ingredients
– A Cutout Person
– EVEN function
At least 2 from the following:
– LET function
– Dynamic Arrays
– Custom Data Type
– LAMBDA function

In this video, I combine the ingredients into a workbook that helps manage and price dirty jobs in a post-apocalypse world of weirdos and chaos.

Multiple Dropdown Lists | Dynamic Arrays | Filter Function

Dependent Dropdown Lists in Excel are pretty handy to know. But there’s an interesting problem when you’ve gotta stack multiple dependent dropdown lists and the source data might add or remove data in the different stages.

This video shows how to make this happen using Dynamic Arrays, UNIQUE and the FILTER functions.

Also check out Leila Gharani’s recent video that has a slight variation and she shows a Google Sheets solution. https://youtu.be/ku17vgq4Q14

8 Warnings about Excel Wolfram Data Types | Linked Data Types | Excel Rich Data Types

The new Wolfram Data Types are pretty interesting, but there are things that you have to watch out for. This video is a sampling of 8 things that are weird about the data types and how they work within Excel.

1:19 Fascinating and Incomplete Entries
2:12 Unexpected Translation
3:29 False Negatives. When looking for a movie, the result was “no data found.” But, I was able to find it.
4:15 Sometimes results take up several cells. You’ve gotta watch for the data to show vertical or horizontal.
6:04 No Sports Data. On the Wolfram site sports data is available. But it’s not available to import into Excel.
7:10 Watch Your Measurements. I imported the heights of celebrities. It was in meters and had to be converted to feet & inches.
8:17 Paste-as-Values and Flash fill don’t work with Wolfram Data Types.
9:47 Names don’t equal Names. Be careful. Do you want a celebrity’s birth name (Paul Hewson) or the name they go by (Bono)?

Build a Solution from Scratch | Dynamic Arrays & Conditional Formatting | Excel Turbo Challenge

NOTE: this videos shows how I build a solution from scratch.

Cristiano Galvão of Excel Turbo posted something fascinating on LinkedIn. He had a main table of data and one column showed each record as Active or Inactive. There were two interesting things about the spreadsheet:
1. If a record was Inactive, the font was automatically gray. If it went from Inactive to Active, the font returned to normal.
2. Inactive records automatically populated on an Inactive worksheet. Active records automatically populated on an Active sheet. If a record changed statuses, it would automatically move to the right sheet.

I was intrigued. 💡🤔

I wanted to recreate this solution but I also know that records don’t always fit into neat categories. So, the solution in this video includes a 3rd category: Unassigned.

In this video you’ll see me figure this out for the first time, and watch my development process. That is more important than the actual solution. I didn’t work the solution out ahead of time and I don’t start with any data.

You get to see the whole process … from the creation of fake data, to the final working model.

XLOOKUP Partial Match with Numbers | the Multiply by 1 Trick | Getting Good with Excel Takes Time

I got a plea one night from someone who needed to match some numbers. He had the right instinct but he stumbled up on a situation where you just have to have seen a lot of Excel over a long period of time to know about this hack.
He needed to match the first 4 numbers in an 8-number string.

He tried the VLOOKUP and LEFT functions. But he didn’t know about the “Multiply by 1 Trick.” You’ll see that trick in this video, but I use XLOOKUP. We’re all about being modern over here. 🤗🤩😁🌶

2 Custom Data Types | 1 Dataset | 1 Warning

Custom Data Types in Excel and Power Query are pretty interesting. In this video I continue to explore them.
1. We add 2 Custom Data Types in a single dataset.
2. In situations where a merge/join has to happen, it’s best to do the merge first, and then create the Custom Data Type.

1:25 Introducing the data and challenge
2:20 Going into Power Query to clean the data: Column by Example, Split Column into Rows
3:29 Warning: merge before creating custom data types
4:00 Merge: Left Outer Join
4:37 Create the Students Custom Data Type
5:32 Create the Advisors Custom Data Type
6:46 Correcting and updating the data
8:30 Detailed warning about creating Custom Data Types before merging datasets.
9:41 Outro

You’ll also see:
– Column by Example
– Split column by delimiter
– Split columns into rows
– Left Outer Join
– Right Outer Join
