Rename Worksheet

Hi,

What is the syntax to rename excel worksheet present in testing.xls

Suppose my excel name is testing.xls
The worksheet name is sheet1.

I want to change this worksheet name from sheet1 to TAB11.

Thanks in advance.

You just select the text in the tab, backspace over the "sheet1" and type whatever you want. But I have no idea how to do it with a shell script. Is this really a shell scripting question?

I suppose the closest "parallel" we could make this to a "Shell Scripting" question would be to export the .xls file to an .xml file (a "Save As" option of Excel), modify that, then import it back to Excel?
