In Microsoft Excel, you may see any of the following behaviors:
  • The name of the workbook may contain either of the bracket characters: [ ]


  • The name on the sheet tab for the workbook contains the file name extension and a ] character preceding the sheet names, for example, .xls]Sheet1


  • When you rename a sheet that contains the file name extension and ] character, you receive the following error message:
    While renaming a sheet or chart, you entered an invalid name. Try one of the following: - Make sure the name you entered does not exceed 31 characters. - Make sure the name does not contain any of the following characters:    : \ / ? * [ or ] - Make sure you did not leave the name blank.						
These behaviors may occur when you do either of the following:
  • You programmatically save a file with a file name that includes the [ or ] characters.

  • You open a file that was renamed outside of Excel, with a file name that includes the [ or ] characters.
To work around this problem, save the file using a new name without [ or ] characters.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
More information
When you programmatically save a file, Excel does not validate the file name by checking for either the [ or ] characters. Therefore, Visual Basic for Applications allows you to save a file with either or both of these characters.
