Hi, i have an excel sheet that contains english and tamil. But the tamil content is not displayed properly (symbols, characters). This is a font problem, but how do i solve it? Is there a multilingual font available?

I have to believe this is something you'd solve in Windows, not Excel or even in Office. I myself like to display a lot of fonts and to read web pages in languages other than English; I enable the other scripts in the Control panel. Let's see: Control Panel; Clock, Language, and Region; Region and Language; select the Keyboards and Languages tab; hit the Change Keyboards button. It may take a little experimenting to figure out how to use the resulting dialogue; feel free to ask again if you run into problems, though you may want to do it in the (much less active) Windows forum instead. But I suppose Excel gets from Windows a list of available languages and the keyboards you want available for each one, so once you've done that you may automatically start seeing what you want in Excel.

Oh, wait, I see more: Once you've enabled languages and keyboard in the Control Panel, back in Excel go to File, Options, and select the Language tab on the left. It says you can add "additional editing languages there; maybe you don't need to go through the Control Panel after all.
