Changing Link References

An ExcelTips reader wrote about a problem their company was having with links in their workbooks. It seems that their links were showing up as UNC paths to files instead of as mapped drive letters. This initially posed no problem, but when the files were moved to a new network server in preparation for changing the network configuration, the UNC paths no longer worked.

Fortunately, Excel has a very powerful search and replace feature. It is so powerful, it even works on OLE links in your worksheet. For instance, let's say your links in some cells looked like this:

='\\proserver\Excel\mystuff\[WordTips.xls]Sheet1!B25

If the server name is changing, or the data is being moved to a different server, this can present a problem. And, unfortunately, the Links option from the Edit menu is a real pain at times. You can quickly change all UNC references in the worksheet by searching for the UNC path (in this case, "\\proserver\Excel\mystuff\") and replacing it with your desired mapped drive letter (for instance, "q:\"). The result is links that all of a sudden point to the proper location.

There is one "gottcha" to be aware of. The UNC path is very specific, and will work regardless of what computer is connected to a network. However, it is possible for different computers to have different drive letters mapped for the same network destination. For instance, one workstation might have \\proserver\Excel\ mapped to drive S:, and another workstation may have it mapped to T:. If you change all the links to S:, then the workstations that don't use drive S: for mapping to that location will not be able to access the file.
