Excel Recalculation • • 9 minutes to read • Contributors • • • • • In this article Applies to: Excel 2013 Office 2013 Visual Studio The user can trigger recalculation in Microsoft Excel in several ways, for example: • Entering new data (if Excel is in Automatic recalculation mode, described later in this topic). • Explicitly instructing Excel to recalculate all or part of a workbook.

VBA - turn on auto calculation AFTER Workbook is closed. Run a sub to set calculation back to automatic on a time delay so that it runs after the workbook has.

• Deleting or inserting a row or column. • Saving a workbook while the Recalculate before save option is set.

• Performing certain Autofilter actions. • Double-clicking a row or column divider (in Automatic calculation mode). • Adding, editing, or deleting a defined name. • Renaming a worksheet. • Changing the position of a worksheet in relation to other worksheets.

Note This topic does not distinguish between the user directly pressing a key or clicking the mouse, and those tasks being done by a command or macro. The user runs the command, or does something to cause the command to run so that it is still considered a user action. Therefore the phrase 'the user' also means 'the user, or a command or process started by the user.' Dependence, Dirty Cells, and Recalculated Cells The calculation of worksheets in Excel can be viewed as a three-stage process: • Construction of a dependency tree • Construction of a calculation chain • Recalculation of cells The dependency tree informs Excel about which cells depend on which others, or equivalently, which cells are precedents for which others. From this tree, Excel constructs a calculation chain. The calculation chain lists all the cells that contain formulas in the order in which they should be calculated. During recalculation, Excel revises this chain if it comes across a formula that depends on a cell that has not yet been calculated.

In this case, the cell that is being calculated and its dependents are moved down the chain. For this reason, calculation times can often improve in a worksheet that has just been opened in the first few calculation cycles. When a structural change is made to a workbook, for example, when a new formula is entered, Excel reconstructs the dependency tree and calculation chain. When new data or new formulas are entered, Excel marks all the cells that depend on that new data as needing recalculation. Cells that are marked in this way are known as dirty. All direct and indirect dependents are marked as dirty so that if B1 depends on A1, and C1 depends on B1, when A1 is changed, both B1 and C1 are marked as dirty. If a cell depends, directly or indirectly, on itself, Excel detects the circular reference and warns the user. Iso 9001 pdf deutsch kostenlos.

This is usually an error condition that the user must fix, and Excel provides very helpful graphical and navigational tools to help the user to find the source of the circular dependency. In some cases, you might deliberately want this condition to exist. For example, you might want to run an iterative calculation where the starting point for the next iteration is the result of the previous iteration. Excel supports control of iterative calculations through the calculation options dialog box. After marking cells as dirty, when a recalculation is next done, Excel reevaluates the contents of each dirty cell in the order dictated by the calculation chain. In the example given earlier, this means B1 is first, and then C1. This recalculation occurs immediately after Excel finishes marking cells as dirty if the recalculation mode is automatic; otherwise, it occurs later.
