Office 365 Excel: Worksheets to workbook

Hi all,

I have been trying to find a way to make worksheets into workbook within Teams & Excel web version.

In desktop Excel, I can do copy & move to make sheet into a workbook.
Or use VBA to make multiple sheets into workbooks.

But I have find a way to do this within Teams or Excel Web.

Is this function not available or limited?

Thank you in an advance.
