The information in this article applies to:
In the versions of Microsoft Excel listed above, you may receive the following error message when you try to rename a sheet tab:
While renaming a sheet, you entered an invalid sheet name. The
following are possible reasons for this:
The error message then goes on to explain potential reasons why the error
is occurring.
This error message occurs if you open a text file whose name contains a right bracket character (]) and then try to rename the file's sheet tab.
To avoid this problem, make sure your text file name does not contain a right bracket character (]) before you open the file in Microsoft Excel. Preferably, the file name should also not contain a left bracket character ([).
In Microsoft Excel, the left and right bracket characters ([, ]) have special meaning. In worksheet formulas, they are used to separate the workbook name from the names of sheets contained within the workbook. For example:
=[Book1.xls]Sheet1!$A$1
If you open a file whose name contains either a left or a right bracket,
Microsoft Excel may mishandle the file's name, causing the problem
described earlier. Note, a file whose name contains a left bracket
character but not a right bracket character should not be affected by this
problem.
