When you are working with multiple workbooks or worksheets, it is often needed to refer back or retrieve data from different workbooks into the current workbook. This helps to keep your work modular and less complex. In LibreOffice Calc, you can achieve it using an external reference.
External reference, as its name says, a reference to an external file (workbook) or a cell inside that workbook. And the reference can be of any form with a fully qualified path with folders or servers.
There are two types of external reference which you can do it in Calc.
- Calc reference to another sheet.
- Calc reference to another workbook.
