Managing Worksheets

Gnumeric provides a number of options for manipulating worksheets as a whole, rather than the contents of the worksheets. These operations are documented in the later section Worksheet Tab Context Menu. In addition to the worksheet tab context menu and the Sheet submenu of the Edit menu, some of these operations are also available from other menus:

In addition to worksheet manipulation, Gnumeric provides the ability to control various aspects of how or whether a worksheet is displayed in the cell grid. Several such controls are included in the Manage Sheets dialog, described in a later section. Other worksheet display controls are located in the Format ▶ Sheet submenu, which are described there.

Except for the addition of the two Select submenus, which appear only on the context menu, this is the same as the Edit ▶ Sheet submenu. The Manage sheets... dialog is discussed in Manage Sheets dialog, which follows the description of the context menu.

The Manage Sheets dialog can be accessed from the worksheet tab context menu, from the Edit ▶ Sheet submenu, or from the Format ▶ Sheet submenu.

The worksheets contained in the current workbook are listed in the upper left portion of the dialog. When Show advanced sheet properties is enabled, the Dir, Rows, and Cols fields are included. A worksheet can be selected by clicking anywhere in its line, although clicking one of the icons will toggle its associated property along with selecting the worksheet. Multiple selection, using the Shift and Ctrl keys, can be used to operate on more than one worksheet at a time. The current worksheet shown in the cell grid tracks the selected worksheet in this dialog. That is, selecting a single worksheet from the list also causes that worksheet to be displayed in the cell grid. When more than one worksheet is selected in the list, the first one in the list is set as the current worksheet in the cell grid. Some operations are not available when more than one worksheet is selected. The buttons for those operations are dimmed when they are unavailable.

The Lock column of the list shows an icon to indicate whether the worksheet is locked,

, or unlocked,

. Click on the displayed icon to toggle the sheet's lock status. Locking a worksheet prevents accidental modification of the data on that worksheet.

The Viz column of the list shows an icon,

, if the worksheet is currently visible. The Viz column is blank if the worksheet is not visible. Click in this column to toggle the worksheet's visibility. When the visibility attribute is turned off, the worksheet does not get a tab at the bottom of the Gnumeric window. Its data is preserved, and references to cells on the non-visible sheet continue to access the expected values. Note that a non-visible worksheet cannot be selected from the list, although the active fields in the list continue to function. To apply functions that require selecting the worksheet, such as Insert or Remove, first click in the Viz column to make it visible.

The Dir column of the list shows a right-pointing or left-pointing arrow, depending on whether the sheet is currently set to be displayed left-to-right or right-to-left. Click on the arrow to toggle a worksheet's display direction.

The Rows and Cols columns show the current size of each worksheet. Worksheet size cannot be adjusted here.

To change the name of a worksheet, click in its New Name field until the contents of the field, if any, are highlighted, then type the desired new name and press Enter. If the new name duplicates a name already in use, a warning is displayed. You can change the new name or you can assign a new name to the other worksheet with that name. Name changes are not applied immediately. Instead, Gnumeric waits until you click on the Apply Name Changes button and makes all the name changes at once. When you apply the name changes, Gnumeric automatically updates all cell references that include worksheet names to use the new names.

The worksheets can be re-ordered in the workbook by pressing the left mouse button in a worksheet's line and dragging it up or down in the list of worksheets. You can also select a single worksheet and then click on the Up or Down button to move it up or down in the list. Alternatively, you can sort the worksheets into ascending or descending order by name by clicking on the Ascending or Descending button.

You can add an empty worksheet by clicking on Insert, to add the worksheet ahead of the selected worksheet, or on Append, to add the worksheet after the last sheet in the list. Insert creates a new worksheet the same size as the currently selected worksheet, while Append creates a new worksheet of the default size.

Click on Remove to delete the currently selected worksheet or worksheets.

Click on Duplicate to add an exact copy of the selected worksheet to the list immediately following the selected sheet. The name of the new worksheet is the same as the name of the duplicated worksheet, but with “(n)” appended, where n is the smallest integer greater than 1 that produces a unique worksheet name. If the worksheet name already ends in “(n)”, nothing is appended. Instead, the value of n is increased to the smallest value that produces a unique worksheet name.

To change the background color of the tabs for the selected worksheets, click on the background color fill button,

to set the background color to the color shown below the bucket icon, or click on the downward-pointing arrow to access the color selection dialog.

Similarly, to change the color of the text in the tabs of the selected worksheets, click on the text color button,

to set the text color to the color shown below the character icon, or click on the downward-pointing arrow to access the color selection dialog.

A new, empty worksheet can be added to a workbook by insertion ahead of the worksheet currently displayed in the cell grid or by appending one after the last worksheet.

A new worksheet can be inserted ahead of the current worksheet by selecting Sheet from the Insert menu or Insert from the worksheet tab context menu or by using the Insert function of the Manage Sheets dialog described above. The new worksheet will be the same size as the one currently displayed.

A new worksheet can be added to the end of the list by selecting Append from the worksheet tab context menu or by using the Append function of the Manage Sheets dialog described above. The new worksheet will be the default size.

Gnumeric does not directly support copying and pasting of worksheets, however copying blocks of cells provides a very similar function. For example, to replace the contents of worksheet Sheet3 with the contents of Sheet1, begin by selecting the worksheet tab for Sheet1. Select all the cells in Sheet1 by clicking on the blank rectangle at the top of the row headers, to the left of the column headers, or by selecting Select ▶ All from the Edit menu. Next use Edit ▶ Copy or Edit ▶ Cut to copy the worksheet contents to the clipboard, depending on whether you want to copy or move the information. Select the worksheet tab for Sheet3 and select cell A1 or the entire worksheet, then use Paste or Paste Special from the Edit menu to copy the contents of Sheet1 into Sheet3.

A similar operation can be performed using the Manage Sheets dialog. Duplicate the worksheet to be copied, then move the copy to precede or follow the worksheet it is to replace. Delete the second worksheet and rename the copy. This operation is similar to the copy and paste technique described above, but this method also copies metadata, such as the display appearance controlled by the Format ▶ Sheet submenu.
