set font syntax in printf for an excel file

[dvsmas]

I need to send a report as an email with an attachment in an excel sheet format. Using awk, I could reformat the report ,with a "\t" in the printf statements as this is recognised as the cell separator in an xls file.
Is there any way I can set the font attributes also in a similar way?
This means I must give some character in printf so that it is recognised as a BOLD or so-and-so color when the xls is opened.
Thanks for any help

No way to implement it using standard printf function.
And I haven't heard the printf function which has
some capability to change output font.

There you should(I'd say must) use COM technology. John Fill
