Recalculation of formulas

Product: MyOffice Standard. Home Edition

Application: Spreadsheet Home Edition

Calculation is the process of calculating formulas and then displaying the values of the results in cells. Formulas are usually recalculated automatically when the values in the cells on which they depend change. This is a standard procedure when opening/closing a file and editing it.

If there are a large number of formulas in a document, their automatic recalculation can make opening and working with the document difficult. In order to speed up work with such documents, MyOffice Spreadsheet provides a mode in which formula recalculation is done upon user request.

Automatic recalculation mode	Manual recalculation mode
•When a user opens and saves a document, only the outdated formula values are recalculated. •When you work with a document, formulas are recalculated if the associated cells have been changed.	•When you open a document and change the associated cells, no formulas are automatically recalculated. •When you work with a document, formulas are recalculated only when you carry out manual operations on the cells that contain them. •Manual recalculation of outdated formula values is available in the entire document, on the sheet, and in selected cells. •When saving a document, recalculation of outdated formula values is performed only if the Before Saving box is checked.

Automatic recalculation mode

Manual recalculation mode

•When a user opens and saves a document, only the outdated formula values are recalculated.

•When you work with a document, formulas are recalculated if the associated cells have been changed.

•When you open a document and change the associated cells, no formulas are automatically recalculated.

•When you work with a document, formulas are recalculated only when you carry out manual operations on the cells that contain them.

•Manual recalculation of outdated formula values is available in the entire document, on the sheet, and in selected cells.

•When saving a document, recalculation of outdated formula values is performed only if the Before Saving box is checked.

Outdated values in formulas are irrelevant data that were calculated in the past but are no longer relevant. They may occur as a result of data entry errors, errors in formulas and functions, data type mismatches, changes in table structure, errors in macros, or synchronization problems. MyOffice Spreadsheet stores information about the presence of such cells within the file itself.

When recalculating formulas, references to data from external documents are not updated. To update them, follow the steps described in the Update data section.

In automatic mode, only outdated formula values are recalculated when opening a document. If you want to force recalculate all formulas in the document, press Ctrl+Shift+F9.

Recalculate formulas manually

You can manually recalculate outdated formula values in the entire document, on an open sheet, or in selected cells.

To recalculate outdated formula values in the entire document, do one of the following:

•In the Command menu, select Data > Calculation Mode > Calculate > Whole Document.

•On the Toolbar, in the Data section, click the recalculation area selection button and select t_data_calculate_whole_document Whole Document from the drop-down list.

•Press F9.

To recalculate outdated formula values on a sheet currently open, do one of the following:

•In the Command menu, select Data > Calculation Mode > Calculate > Calculate Sheet.

•On the Toolbar, in the Data section, click the recalculation area selection button and select t_data_calculate_sheet Calculate Sheet from the drop-down list.

•Right-click the sheet tab and run the Calculate Sheet command from the context menu.

To recalculate outdated formula values in one or more selected cells, do one of the following:

•In the Command menu, select Data > Calculation Mode > Calculate > Calculate Selected Cells.

•On the Toolbar, in the Data section, click the recalculation area selection button and select t_data_calculate_selected_cells Calculate Selected Cells from the drop-down list.

Recalculate formulas when saving a document

When the user saves the document, recalculation of outdated formula values is carried out if the Before Saving box is checked.

In Automatic mode, the Before Saving box is always checked and locked.

In Manual mode, the Before Saving box is checked by default. If you want to uncheck the box, do one of the following:

•In the Command menu, select Data > Calculation Mode > Calculate and uncheck the Before Saving box.
