You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Can I use dynamic arrays?

This series of blog articles dangles lots of enticing software goodies in front of you, but it's possible that you won't be able to use them!  Here's a guide to who can share in the new era.

A quick test

The quickest way to find out if you have dynamic arrays is to type in the start of a formula:

Sort function

If these two functions appear when you type =SORT, you're in business!


This is because these are 2 out of the 7 new functions which accompany dynamic arrays. 

When will I get dynamic arrays (Office 365 users)?

If you can't see the two functions shown above and you're using Office 365, everything is down to your update channel.  To find out what this is, choose this option at the bottom of the File menu in Excel:

File / Account menu

Choose to show details of your Excel account from the File menu.


You should now see which version of Excel you're using:

Office version

This shows that I'm using Office 365 Business.

If you're using Office 365 ProPlus you'll be either on the monthly or six-monthly update channel.  You can understand update channels (and see how to swap between them) here (this link also shows you how to force updates).

When will I get dynamic arrays (Office 2016 and 2019 users)?

You won't - sorry! Dynamic arrays are only available if you subscribe to Microsoft Office, rather than buying the software outright.
