Calc knows 6 different types of links to some other files' content. 4 of them appear in the Edit>Links dialog.
1) ='file:///path/name.ods'#Sheet.A1:B99 (spreadsheets)
2) =DDE("soffice";"C:\path\name.ods";"Sheet.A1:B99" (Calc, Writer and sometimes other DDE sources)
3) menu:Insert>Links to external data (named areas in sheets and html tables)
4) menu:Insert>Sheet_From_File with link option (whole sheets of all file types supported by Calc including csv)
5) Databases connection (drag&drop from data source window)
6) Pivot tables connected to a data source
Edit: 7) Linked images attached to the draw page layer of an ODF document |
For 1) and 2) you need to edit all formulas where the link is in use. Otherwise they reappear in the links dialog with every recalculation.
3) and 4) can be removed in the links dialog.
5) can be removed in Data>Define...
6) goes away when removing the pivot table
Edit: 7) You can break the link in the Edit>Links dialog of Writer, Calc, Draw and Impress. The list box with the links is a multi-selection box. Ctrl+A selects all links. |
