The New & Improved RANDARRAY Dynamic Array Function

Lordy! This is a good one! Just within the past week the RANDARRAY function was improved! Dynamic Arrays, the functions and the new calculation engine just keep getting better.

RANDARRAY. WOW! This is better than both the old RAND and RANDBETWEEN functions!

This video shows 2 examples of using RANDARRAY. In the olden days, we would have needed more than just this one function. You will also see RANDARRAY used with INDEX and COUNTA! Everything you possibly could need … it’s all here, brothers and sisters. It’s all here, and it’s FIRE!

Dynamic Array: Unstack Data with SEQUENCE … just 2 steps

Here we are again!
I was playing around more with the Dynamic Array functions, especially after Leila Gharani posted her video that made unstacking data pretty easy with a substitution trick and finding a pattern in the dataset. Here is her video:

Well, I found a 2-step process that REALLY simplifies unstacking a column of data. SEQUENCE, COUNTA and INDEX get us there, taking advantage of spilled arrays and Excel’s new calculation engine. Alas, not everyone has the Dynamic Arrays yet. If you don’t have them, and you need to unstack some data, use Leila’s method. 👍

Excel Dynamic Arrays: 4 Complex Filter Examples

Excel’s Dynamic Arrays are fascinating … and complex. Here is a second video where I dig into the logic of the FILTER function.

You’ll see examples of the FILTER function, filtering on 2 criteria where I play with the logical operators:

Greater Than
Less Than
Equal To
Not Equal To
Smaller Than or Equal To

Excel Dynamic Arrays: FILTER for Optional and Required Fields

The new FILTER function is fantastic, but I wondered how can I make an optional field?

Sometimes we do searches and want to look at items between $10 and $100 for brand X.

We also want to look at everything between $10 and $100 regardless of the brand.

That’s what I wanted to replicate with the FILTER function: an optional filter. The straight-forward FILTER function forces us to filter for something whether we want to, or not.

My solution involves using an IF statement and smart use of the # nomenclature. Check it out!

Excel Dynamic Arrays: Unstack a Column of Records

The classic problem: unstack a column of records in Excel.
This video shows a cool way to get this stuff un-stacked. You’ll see the FILTER Dynamic Array function, the SEQUENCE Dynamic Array Function, and even the SORTBY.

You’ll see cool uses of regular Excel functions that act like arrays. This is real fire, baby!

Power Query: Keep all Capital Letters with Text.Select in M-Code

Rahim Ali asked me about how to keep only capitol letters. For example:

France: F
United States: USA
Republic of China: ROC
United Arab Emirates: UAE
South Korea: SK

(In this video I use names as examples to work with.)

This can be done with Excel’s Flash Fill but that’s not a dynamic solution. For something dynamic we use Power Query and it’s a little tricky and we make clever use of Add Column from Example.

We have to go into the m-code and convert:
Text.Remove to Text.Select. And then we can have Power Query select only A thru Z

And then … a TWIST!

We’ve got a problem with the character: É

I show you one way of dealing with that!

This video also includes a summary of Excel Days 2018 in Sofia, Bulgaria where I had the pleasure to give the keynote presentation and teach a 7-hr Master Class on Excel and Power Query.
