Here are four shortcuts that I find amazingly useful when using spreadsheets with array formulas: 1. I always think “no it’s not okay Microsoft, that is really frustrating” so prefer to hit Escape to exit this message. This happens to the best of us! Luckily, noting really bad happens, but you need to get used to the frustrating pop-up: Even the most advanced and careful Excel wizards will occasionally forget that they are in an array.We also choose to highlight the top left hand cell of an array. Format array areas in your spreadsheet consistently to provide a visual cue as to where your array formulas are. This is less onerous if you copy the existing formula as a text string first (select in the formula bar and use CTRL+C):ĬTRL+C to copy the formula as text from here Formatting Then select the new, smaller range, and re-enter the formula. To shrink the range that an array formula writes to, you will have to delete the whole of the original range (CTRL+/ to select).Then use the Three Finger Salute to confirm the new, larger array. Select the expanded range that you want to write to. To expand the range that an array formula writes to, start with the formula in the top left hand corner.The array formula will appear in all other cells of the range, but it cannot be edited in any cell other than the top left hand corner of the range. This is the only cell within the range that can be edited. The array formula itself always resides in the top left hand corner of the range.To delete an array formula you must highlight the entire area of the spreadsheet where the array is entered.Remember to enter your formulas using the Three Finger Salute CTRL+SHIFT+ENTER.Here are some things to remember: Entering an Array Formula Working with Array FormulasĪrray formulas act a little bit differently to other Excel formulas.

These curly brackets are how Excel recognises an array formula.
This will produce curly brackets around the formula. Press CTRL+SHIFT+ENTER to confirm this formula (instead of just pressing ENTER).Select the area on your spreadsheet that you want to return the data to.Entering An Array FormulaĮntering an array formula in Excel is a little bit different to your run of the mill formulas: All of the data returned in an “array” can therefore be displayed in a single area of a spreadsheet, so long as it is the correct size. These arrays are only ever two-dimensional. Most people would refer to this as a “matrix” but Microsoft choose to refer to these as arrays. The Excel output is therefore a rectangle of values ( x rows by y columns). However, some formulas do not return a single value. This means that you can type a formula in a cell, and within that same cell the result of the formula is returned – normally as a single value (or some text). What is an array formula?Įxcel functions typically return a single value.

Here is how to work with array formulas in Excel. To implement this in Excel, we must use “array formulas”. The results that are returned are not necessarily single values – we return a grid of results ( x rows by y columns). Then we send the results back to your Excel spreadsheet. Send us the function name and parameters and we do the rest remotely. It is quick, simple to use and reliable.Ĭloud-hosted analytics are made available to users via a data connection in Excel.
