what cells in excel are linked to other file
When you link a cell in Excel to a cell from another worksheet, the cell that contains the link shows the same data as the cell from the other worksheet. The cell that contains the link is called a dependent cell. The cell in another worksheet that contains data to which the link refers is called a precedent cell. Dependent cells automatically change if the precedent cells change. If you want to link multiple cells from another worksheet, you can use an array function, which lets you link a range of cells using one formula. Click the worksheet tab at the bottom of the screen that contains a range of precedent cells to which you want to link. A range is a block or group of adjacent cells.
