What is the Excel hotkey to re-calculate all formula in sheet? There is a part where you can ask excel to automatically update them once you have a new input. Microsoft Excel is a powerful tool for businesses, and it is one of the most widely used spreadsheet programs around. But to get the most from this popular program, you need to learn to use its. The Excel Options dialog box displays. Click “Formulas” in the list of items on the left. In the Calculation options section, click the “Manual” radio button to turn on the ability to manually calculate each worksheet. When you select “Manual”, the “Recalculate workbook before saving” check box is automatically checked. To control when Excel calculates your worksheet, you click the Calculation Options button on the Formulas tab of the Ribbon and then click the Manual option button or press Alt+MXM. After switching to manual recalculation, when you make a change in a value, formula, or name that would usually cause Excel to recalculate the worksheet, the.

- How to Turn Off/On Microsoft Excel's Calculation Mode. Microsoft Excel has the capability for a user to control its workbook calculation mode. A user will set this mode to manual disabling all calculations when a workbook takes a long time to calculate when new values are entered.

I followed this guide to create the following custom function which counts the number of cells of a certain colour in my spreadsheet:
It works fine and gives me the expected result if I click the green tick in the formula bar but won't update automatically after I colour another cell. How do I set it to automatically update the count every time I manually colour a cell elsewhere on the spreadsheet?
Extra info: I'm using Excel on the Mac and I've checked in settings and automatically calculate is turned on.

Excel Recalculates UDFs Only When Their Input Changes
You've created a User-Defined Function (UDF). Excel only runs the code of a UDF when the cell(s) that serve as input to the function change.
For example, suppose I have this UDF:
And in cell A1 on my worksheet I reference the cell with the formula:
During normal use of my workbook, the code of my UDF will only be called if there's a change to the contents of cell A2 or another cell referenced by a formula in A2.

You can work around this behavior in several ways:
- Force Excel to manual recalculate all of the formulas in the workbook even if they have not changed since the last calculation by pressingCtrl+Alt+F9 on Windows and (I assume on Mac) Cmd+Alt+F9. If that doesn't work you can also try adding Shift which additionally rechecks dependent formulas before recalculating.
- Include a volatile function in one of the cells referenced by your UDF. Do this by modifying the definition of your VBA function to accept an additional parameter:Then edit the cell referencing your UDF to pass the result of a volatile function such as
Now()
to the UDF:The net result will be that Excel will deem the cell containing the reference to your UDF as needing to be recaculated every time the worksheet is changed because it references a volatile function. - Edit the cell containing the UDF. Simply entering the cell then pressing Enter without making changes should be sufficient to trigger an update.
- Create macro button that runs the following line of code:
- Place the following code in your Workbook's Open event:This causes Excel to always recalculate all formulas, regardless of whether it believes recalculation is required. This setting remains in effect until Excel is restarted.
Why Doesn't Excel Always Recalculate My UDF?
When Excel performs an automatic recalculation, it does not recalculate every single formula in the workbook. Instead it only updates those cells which contain formulas that refer to the most recently modified cell. This method avoids the much lengthier process of needlessly performing many calculations across the entire workbook only to come up with the same result for the vast majority of them.
With a UDF, the only references in the workbook of which Excel's calculation engine is aware are those identified in the function's inputs. Excel cannot examine the VBA code within the UDF and identify other cells that may influence the function's output. So while the function's author may construct the function to return different results based on any number of changes made in the workbook, the only cells Excel knows will change the function's result are the declared inputs. Therefore, changes to these cells are the only ones Excel pays attention to when deciding whether the UDF needs to be recalculated.

I hit this while hoping to update all user defined functions whenever an ActiveX textbox was changed even if they didn't affect linked cells which were used as inputs to the UDF. By accident I discovered that including any indirect cell reference in the function call appears to make it run whenever (seemingly) any other cell is edited. Presumably this is because excel has fewer guarantees about what it can trust to be unmodified when an indirect modifier is used. This is similar to Twisty Impersonator's second answer but adds less cruft to your vba code and formulas (so long as as least one range is used in the function).
Example: This function should always return the value in 'A2'
If you call it like
=test(B1)
it will not updated whenever A2 changesIf you call it like =test(INDIRECT(ADDRESS(ROW(B1),COLUMN(B1)))
it is functionally equivalent, and will update whenever A2 changes.=test(INDIRECT('B1'))
will also work and may be cleaner to understand for this example, but because 'B1' is a string you won't be able to copy the formula across new values. dchu58dchu58
Format changes (which includes Color Changes) are not considered events worthwhile a recalculation in Excel. That is not related to user defined functions. Therefore, any format change will not result in a recalculation.
That is not arbitrary, but makes some sense, as normally format changes do not influence anything else, so a recalculation - which is expensive - would be wasted. Since Excel now allows VB to use format information and react to it, this can become an issue, as it is for you.
You might be able to set OnChange functions for all cells, and trigger a recalculation there, but a format change might just not fire this function either (I never tried).

None of these worked for me. I found that the only way I could get my UDF to calculate was to add the code below to the worksheet.activate event and point the focus to another sheet on open. Then when I clicked on the tab to the main sheet it worked.
