1. Calculate and recalculate data in Excel Services
Applies to: Microsoft SharePoint Server 2010
You can use formulas in a workbook in the browser just as you can use them in Excel. Just as in Excel, the
author of the formula determines the way formulas are calculated or recalculated. This article describes
the different options for calculation.
Typically, a workbook recalculates formulas automatically when a value in a cell changes that the formula
depends on. For example, suppose you use a formula to add all the individual values in a column. If you
insert rows in the workbook, and thus add cells to the range of cells in the column, the workbook adjusts
the formula to include the new cells automatically, and recalculates the total.
However, not all workbooks calculate formulas automatically. When an author creates a formula in Excel,
the author can select different calculation options. For example, the author might require that all formulas
have to be re-calculated manually when a user clicks a command. After the author selects a calculation
option and publishes or saves the workbook to a document library in Microsoft SharePoint Server 2010,
the published workbook keeps the calculation option that the author specified in the Excel workbook.
The following table provides a brief description of the different calculation options.
CALCULATION DESCRIPTION
OPTION
Automatic Formulas are recalculated automatically every time a formula changes, and every
Calculation time that a cell changes that a formula references. This is the default option.
Manual Calculation Formulas are never re-calculated automatically. A user must select the Calculate
Workbook option to recalculate any formulas.
Automatic except Formulas and referenced cells that are contained in an Excel Data Table as part of
Tables What-If analysis are not recalculated.
Other formulas are recalculated automatically every time a formula changes, and
every time that a cell changes that a formula references.
Recalculate Before Formulas are recalculated automatically every time the workbook is saved.
Save IMPORTANT Excel Services does not support this option because you cannot
save a workbook.
If the workbook author configured a workbook for manual calculation, you can take these steps to
calculate the formulas in a workbook in the browser.
1. Open the workbook.
2. On the workbook toolbar, click the Data menu, and then click Calculate Workbook.
Alternatively, you can use the shortcut key F9 to calculate the formulas in a workbook.
NOTES

2. 1. To use formulas in a workbook in Excel Services, the workbook author must create a workbook in Excel
that contains formulas, and then publish or save the workbook to Microsoft SharePoint Server 2010. In
Excel Web App, you can use formulas created in Excel, or you can enter formulas directly in a workbook
just as you do in Excel.
2. If a workbook in the browser contains a formula with a circular reference that cannot be resolved, it does
not display a warning message about the circular reference. Instead, it calculates the values that you
would get if you cancel the operation on the Excel client. In effect, the workbook automatically cancels the
circular reference. This prevents performance degradation that otherwise might result from attempting to
calculate a circular reference.
