![]() And on the other side the silent conversion Excel does to the file.Ībout the brackets particularly, it is not FlexCel that adds them, they are always there. So now in our side we have 2 problems: On one side the stuff that breaks (and that could cause old FlexCel code to break, even if you are not using and don't care about dynamic arrays at all). So what does Excel do? It silently converts the file when you open it, so, in most cases, you will not notice (unless you want to open the file back in the older Excel version, or other spreadsheet like libreoffice). This means that just opening an older file in Excel 2021 could break it. There are other things that break, like for example array intersection, which was automatic before, but now it is not anymore. Or have GetCellValue return a "special" value for C2, so you can know it is not a real value. So what should GetCellValue return for cell C2? The answer is "it depends", and we might need 2 different GetCellValue (one that returns test2, the other returns empty), and you need to know which one to call depending in what you want the value for. But if you are copying it to another sheet, it doesn't, because the formula is only in cell C1. In your example, cell C2 is grey in Excel, and if you are printing it, it has a value (test1). Some cells now have " Schrödinger values" and they might or not might have a value depending on what you want them for. Dynamic arrays change basic assumptions to the spreadsheet, stuff like "A cell either has a value or it hasn't" now is not valid anymore. But lambda functions are just an addition to existing stuff, they don't break it. The feature in itself isn't that hard to implement, in fact, stuff like the lambda functions we already implemented is harder. Going more in depth, Dynamic arrays are a "feature that breaks everything", which to me is a first in all Excel history. (you'll get the same curly brackets if you open a file created by Excel in any older Excel version). So FlexCel works as if it was office 2019, or libreoffice. (see Dynamic array formulas in Excel | Exceljet ). ![]() VLOOKUP: Lookup the nth item (without helper columns)ĭiscover how you can automate your work with our Excel courses and tools.In short, the problem is that FlexCel doesn't support yet dynamic arrays.Here are some posts from the blog which include other examples of array formulas. If Ctrl + Shift + Enter is not used, it is likely to display either #VALUE or worse an incorrect result.Most people won’t understand your work (though this may be a good thing).They can be very slow to calculate, and they are often much slower than using a helper column.=MATCH(E14&F14,A2:A13&B2:B13,0) WarningsĪrray formulas may sound great, but there are some issues to be aware of: In the example below Cells E14 & F14 are combined into a single search criterion then compared to A2 & B2 combined, then A3 & B3 combined, then A4 & B4 combined, and so on. You can also create the benefit of helper columns without needing to actually create a helper column. Or Maybe the AVERAGEROWNUMBER (average row number) function: =AVERAGE(ROW(A2:A13)) You will know when it has worked because Excel will automatically show a ” Once the formula has been entered into the formula bar, do not just press Enter, but press Ctrl + Shift + Enter at the same time. The type of array formula we will be using in this example does require Ctrl + Shift + Enter. So, just be aware that Ctrl + Shift + Enter does not apply to all array formulas. There are array functions which do not require Ctrl + Shift + Enter to be used. Often array formulas are entered by pressing Ctrl + Shift + Enter – hence why they are sometimes referred to as CSE formulas. Don’t worry if that concept blows your mind at the moment, by the end of this post it’ll hopefully make sense. Array formula basicsĪn array formula is a calculation which works with an array or series of data. ![]() but secretly you’ll know it wasn’t that difficult. ![]() Your work colleagues will look at you like you’re an Excel genius, they will be mesmerized by the apparently impossible calculation you’ve just performed. Once you’ve grasped the concept of this type of array formula, you’ll be able to apply it over and over again. In this post, I want to introduce to you one type of array formula which is actually pretty easy to understand and can be applied to lots real-life situations. They always seem to crop up in forums as solutions to some tricky formula questions. Have you heard of the mysterious “array formulas”? Do you use them? Or are you like most Excel users, you’ve placed them in the “too hard” pile, never to be seen again.
