Also what I am actually interested in is not the WIDEST entry but whether or not a numeric cell will be displayed as ###### due to less column width.

For numeric columns AutoFit is usually enough. In my sample I tried to set width to 240 (looks like it's close to maximum) if the width was greater than 15 after AutoFit. I did it because I needed to put Excel into DBF and my long description fields were truncated otherwise.
