![]() ![]() ![]() In Legacy Excel, there is no UNIQUE function or VSTACK function, so the formula on this page is not possible. In simple scenarios, you can use a formula based on INDEX and MATCH to extract unique values. For more details on the operation of FILTER with UNIQUE, see this example. In this formula, the LET function is used to store the result from VSTACK in the variable data so that it can be used twice inside the FILTER function without another call to VSTACK. To prevent empty cells from being evaluated by UNIQUE, you can use the FILTER function like this: =LET( If any of the ranges to be combined contain empty cells, a zero (0) will appear as a unique value in the final result. The result is a list of unique values in all three ranges taken together. This array is then delivered to the UNIQUE function, which returns the unique values in the combined range. The combined array has range1 on top, range2 in the middle, and range3 at the bottom: range1 Working from the inside out, the VSTACK function combines all three ranges vertically into a single range: VSTACK(range1,range2,range3) // combine ranges into one To solve the problem in this example, we simply need to nest the VSTACK function inside the UNIQUE function like this: =UNIQUE(VSTACK(range1,range2,range3)) Without VSTACK, it is still possible to combine ranges in a formula, but it is a more complicated formula. The Office Insiders program is free to join in Excel 365. Note: VSTACK is currently a Beta function available only through the Beta channel of Office Insiders. The result from VSTACK is a single array with range1 at the top. To combine more arrays, simply provide more arrays to VSTACK. For example, the formula below joins range1 and range2: =VSTACK(range1,range2) // combines rangesĮach additional array is appended to the bottom of the previous array. The VSTACK function combines arrays or ranges vertically into a single array. The solution is to use the VSTACK function to combine ranges first, before invoking UNIQUE. The challenge in this example is to provide more than one range to UNIQUE at the same time. Like other dynamic array formulas, the results from UNIQUE will spill onto the worksheet into multiple cells. Just give UNIQUE a range, and it will give you back the unique values: =UNIQUE(range) // extract unique The UNIQUE function makes it very easy to extract unique values from a range. However, with the introduction of the VSTACK function, the solution is straightforward. Let’s try it out now.In this example, the goal is to extract unique values from three separate ranges at the same time: range1 (C5:C16), range2 (D5:D15), and range3 (F5:F13). At one time, this was a difficult problem, since UNIQUE is programmed to accept only one array and there is no obvious way to provide another range. They are HStack, VStack, and ZStack, which handle horizontal, vertical, and, er, zepth. If we want to return multiple things we have various options, but three are particularly useful. That might be a navigation view, a form, a text view, a picker, or something else entirely, but it must conform to the View protocol so that it can be drawn on the screen. ![]() When we return some View for our body, SwiftUI expects to receive back some kind of view that can be displayed on the screen. ![]()
