![]() The output is always dynamic - when any change occurs in the source data, the results update automatically. Currently, they are available in Microsoft 365 subscriptions and Excel 2021.ĭynamic arrays are supported in these versions:Īs part of the new functionality, 6 new functions were introduced in Excel 365 that handle arrays natively and output data into a range of cells. Eventually, new dynamic arrays are supposed to completely replace the old-fashioned array formulas that are input with the Ctrl + Shift + Enter shortcut.ĭynamic arrays were introduced at the Microsoft Ignite Conference in 2018 and released to Office 365 subscribers in January 2020. With dynamic arrays, a bunch of new functions have been added to the Excel Function Library and the existing ones started to work faster and more effectively. In fact, this is a groundbreaking change to the entire calculation engine. You type it in just one cell (B3 in our case), press the Enter key… and have the whole rage filled with the results at once:įilling multiple cells with a single formula is called spilling, and the populated range of cells is called the spill range.Īn important thing to note is that the recent update is not just a new way of handling arrays in Excel. Now, see what happens when the same formula is used in Excel 365. In pre-dynamic versions of Excel, the below formula would work for the first cell only, unless you enter it in multiple cells and press Ctrl + Shift + Enter to explicitly make it an array formula: Supposing, you need to multiply two groups of numbers, for example, to calculate different percentages. Let me illustrate the concept with a very basic example. In other words, operating dynamic arrays becomes as easy as working with a single cell. ![]() Now, any formula that returns an array of values automatically spills into neighboring cells, without you having to press Ctrl + Shift + Enter or do any other moves. With dynamic arrays, this rule is no longer true. Even with traditional array formulas, it was necessary to enter a formula into each cell where you want a result to appear. Through over 30 years of history, Microsoft Excel has undergone many changes, but one thing remained constant - one formula, one cell.
