The UNIQUE function has a bit of an issue with blank cells, formulas that return blank cells and zeroes.
If you have a list of numbers that are a text numbers or a combination of text numbers with real numbers there is a technique I covered in this blog post to add them up. But if the range also contains text then the technique won’t work. There is the work around. The solutions below work in the subscription version of Excel. Check the comments section below for a solution for all versions.
I wrote a blog post a while back about outliers and Excel and I thought I would revisit it thanks to dynamic arrays.
Let’s say we need to do some testing and we need 1,000 random dates in 2022.
We can use a new function to make this easy to create and easy to change.
RANDARRAY usually works with numbers but in Excel dates are numbers, so we get it to create random dates for us.
I set myself a challenge to do this in less than minute – see how I went in the video below.
I was recently helping someone with a budget which they had built vertically, with the months going down the sheet. They then asked to display it horizontally, with the months going across the page. In the latest version of Excel this is straightforward.
Years back when I wrote my Excel book, I had to create an index for the book. I shared the file I used including the macro in this post. Recently I thought dynamic arrays could do much of the work for this.
Dynamic arrays allow you to use a function normally built to handle a cell, with a range of cells. The TRIM function can remove extra space characters in cells. So with dynamic arrays it can handle ranges.
On LinkedIn recently someone posted an Excel formula solution lamenting that it was long and complex. That of course was a challenge to me to simplify it.
I covered a solution to sorting and ignoring the sign a couple of years back, but it is time to revisit this thanks to dynamic arrays.
It is now easier to create a distinct count formula in the subscription version of Excel. You can also use a criteria. A distinct count only counts each value once. Duplicate entries are ignored.
A spill range is the result of a dynamic array formula. At the moment that requires the subscription version of Excel.
In Excel your goal should be to have a single formula in a table column that can be copied down the whole column.
The new XLOOKUP function has the ability to spill when you select multiple columns to extract. Even when you do, it doesn’t always spill across.
Recently I have been using more dynamic array formulas and have come across an unusual situation where a date is not treated like a date.
Remember dynamic arrays are currently only available in the subscription version of Excel.
Have a look at the image below.
You can download the example file at the button at the bottom of the post if you want to see it in practice.
Cell B1 is an input cell to set the first date of the sequence.
Cell E1 creates sequential numbers using the SEQUENCE function.
Row 2 has the dates and is formatted as a date.
Row 3 is the problem. If I try calculate the number of calendar days in the month using DAY and EOMONTH functions it gives a value error as if the entry in E3 is not a date.
If I multiply the E2# reference by 1 it fixes the issue as per row 4, but I shouldn’t have to do that.
I have had this is other cases where a number is not treated a number until you multiply it by 1 or perform a calculation with it.
Not sure if anyone else has seen this?
If you want to learn more about dynamic arrays I have a free Webinar Recording plus a pdf manual at the link below.
In budgets, forecasts, financial models and even reporting models repeating the numbers 1 to 12 can be useful. The SEQUENCE and MOD functions can make it easy and scalable.
I wrote a blog post a few years back showing how to add up numbers formatted as text. If you have the subscription version of Excel you have another solution.
One of the frustrations with using array syntax is that you always have to type all the entries between the curly brackets. You couldn’t link to cells. Well that has all changed with dynamic arrays.
In this post I finish off the Calendar matrix by adding holidays.
The SEQUENCE function returns sequential numbers. Let’s see how we can use it to create a Calendar matrix.
The SEQUENCE function returns sequential numbers. Let’s see how we can use it with a list of dates.
Many things that were hard or complex are now much simpler. Creating dynamic drop down lists based on previous selections used to be tricky in Excel. Dynamic arrays make it straightforward.
With the introduction of Dynamic Arrays in all versions of Microsoft 365 (formerly Office 365) it is now a lot easier to use the TRANSPOSE function.
The SUMPRODUCT function has been my favourite function for about 20 years. It is so flexible. Soon it will be redundant thanks to dynamic arrays.
With introduction of Dynamic Arrays in Office 365 Excel has one new formula symbol and another that was previously only use in formatted tables.
Dynamic arrays have the potential to change the way Excel spreadsheets are created. They were released in the January 2020 wave of updates to the Office 365 subscription version.
