Control when external references links are updated Applies To: Less When you create external references also called links , you can control whether the external references stay up to date, and when they are updated.
If another user has changed a value in a cell, Microsoft Excel does not look for the new value unless you tell it to. Learn more about external references The workbook that contains the links is called the destination workbook, and the workbook that is linked to it is called the source workbook.
If the workbook that you have opened called a destination file contains links to other workbooks or files called source files , and the source files have changed, the links in the workbook that you are opening may display information that is out of date. The destination workbook contains the external reference. The external reference or link is a reference to a cell range in the source workbook. The source workbook contains the cell and the actual value that is retrieved and placed in the destination workbook.
Control links to other workbooks When the source workbook and the destination workbook are open on the same computer, links are updated automatically.
When you open a destination workbook, and the source workbook is not open, you may be alerted by the Trust Bar whether to update the links. You can control whether the Trust Bar alerts you, and whether to update all links when the alert does not appear. You can also update only some of the links, if the workbook contains more than one link.
Manually update all of the links or none of the links in a workbook Close all workbooks. If one source workbook is open, and others are closed, the updates will not be uniform.
Open the workbook that contains the links. Manually update only some of the links to other workbooks Close all workbooks. On the Data tab, in the Connections group, click Edit Links. In the Source list, click the linked object that you want to update. To select multiple links, hold down Ctrl and click each linked object.

Even if you specify that Excel should not ask whether to update links, you will still be notified if there are any broken links. Decide whether to update links when prompted at startup There are a number of decisions you can make in the Startup Prompt dialog box.
It is possible to accidentally create a link by moving or copying a range, worksheet, or chart between workbooks. Open the workbook, and then find the links that were created, and either break the link or replace it with a value.
Break a link to a source Important: When you break a link to a source, all formulas that use the source are converted to their current value. Because this action cannot be undone, you may want to save a version of the file.
In the Source list, click the link that you want to break. To select multiple linked objects, hold down CTRL and click each linked object. If the link used a defined name, the name is not automatically removed. You may also want to delete the name. In the Name column, click the name that you want to delete, and then click Delete. If you use an external data range, a parameter of a query may also use data from another workbook.
You may want to check for and remove any of these types of links. Replace a single formula with its calculated value When you replace a formula with its value, Excel permanently removes the formula.
If you accidentally replace a formula with a value and you want to restore the formula, click Undo immediately after you enter or paste the value.
Select the cell that contains the formula. If the formula is an array formula, select the range that contains the array formula. To select a range that contains an array Click any cell in the array range. On the Home tab, in the Clipboard group, click Copy.
