I created a command for Microsoft Excel (most recent version, Microsoft 365) based on a macro recording.

The command is select all cells (clicking the triangle in the upper left corner), and then apply "auto fit column"  ( Home > Format > auto fit column width )

In Excel, the macro generated by performing these actions with the mouse is:

    Cells.Select

    Selection.Columns.AutoFit

Seems straightforward enough. I put this into a command called "auto fit column":

Sub Main

    Cells.Select

    Selection.Columns.AutoFit

End Sub

I added the Excel document object library by pressing ALT+ENTER.

But when I execute the command, I get the following error message from Dragon:

"The macro contains the error:

MyCommand: "auto fit column"

line: 3 

position: 0

Description: (1004) Application specific error. - Invalid flags."

Any ideas?
