Linda asked if there is a way to calculate only the active workbook. When a recalc is performed by Excel, it recalculates all her open workbooks, and if they are very large workbooks it can sometimes take over fifteen minutes to recalc. If she is able to limit what is recalculated, then the process will obviously run faster.
Unfortunately, there is no direct method to just calculate a particular workbook. You can, however, calculate just the active worksheet, if desired. First, set the recalculation mode to manual by following these steps:
Figure 1. The Formulas options of the Excel Options dialog box.
Now the only time your workbook (actually, all your open workbooks) will be recalculated is when you press F9. If you want to recalculate only the current worksheet, then press Shift+F9.
Excel also provides macro functions that allow you to do any of these three things: calculate all open workbooks, calculate a specific worksheet in a workbook, or calculate a specified range of cells on a worksheet. With this knowledge you could create a macro that would loop through all the worksheets in a workbook and recalculate each of them.
The following macro sets the calculation mode to manual (so the other workbooks will not calculate) and then loops through and calculates each sheet of the active workbook.
Sub CalcBook() Dim wks As Worksheet Application.Calculation = xlManual For Each wks In ActiveWorkbook.Worksheets wks.Calculate Next Set wks = Nothing End Sub
If you believe that you may want to calculate different parts of your workbook at different times, you can expand the macro so that it will perform any type of calculation you may want:
Sub CalcWhat() Dim iAnsure As Integer Application.Calculation = xlManual iAnsure = InputBox("1 = Calculate A Used Range" _ & vbCrLf & _ "2 = Calculate This Worksheet" _ & vbCrLf & _ "3 = Calculate This Workbook" _ & vbCrLf & _ "4 = Calculate All Workbooks in Memory" _ & vbCrLf & vbCrLf & _ "Input Your Selection Number From Above" _ & vbCrLf & "Then Click OK", _ "Calculate What?", "Input Number Please", _ 5000, 5000) Select Case iAnsure Case 1 'Range Only Selection.Calculate Case 2 'Worksheet Only ActiveSheet.Calculate Case 3 'Workbook Only For Each wks In ActiveWorkbook.Worksheets wks.Calculate Next Case 4 'All Open Workbooks Application.CalculateFull End End Select End Sub
This macro presents an input box that prompts the user as to which type of recalculation is desired. When the user enters a number from 1 to 4, the desired type of recalculation is performed.

Did previous versions of Excel always calculate every Open Workbook OR is this just a feature of newer versions of Excel? I feel like with 2010 I never ran into this problem as frequently as I do now.

The Sub CalcBook() isn't guaranteed to generate the desired outcome (i.e. a fully calculated workbook). "Sheet1" might contain formulas pointing to cells in "Sheet2", but other cells in "Sheet2" might have dependencies back on "Sheet1" or elsewhere. So, calculating each Worksheet once might not be enough to perform a full calculation on your Workbook, as Excel doesn't look at the whole calculation tree for the workbook and recalculate all precedents from the top down when just doing one worksheet.

A shorter way to launch another instance of Excel:
simply click on the Excel icon on the taskbar while holding down the Shift key.

Another method that I use is to start another of instance. This is done by right clicking the Excel icon on the task bar then click on the Excel application icon whilst holding down the Alt key, do not release until Excel asks if you want to start another instance, click yes. This will then set up another group of workbooks and will only recalculate that group.

I wonder whether this could be the solution to a problem I regularly run into: I'm running Win 7 Pro 64 bit on a 3.2 GHZ i7 960 system with 24 GB RAM and an SSD boot drive (it's a pretty fast system). I often have a workbook open, which has several tabs loaded with formulas. Sometimes when I try to open another workbook I get a Windows error message saying I don't have enough memory to open the workbook, which on paper seems ludicrous.
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
