It worked! Can I then save it in the compatibility mode for other people with
2003 version to see?

Yes.

Save the file as a normal (xl2007) style workbook.
Then close it and reopen it.

I am using Excel 2007 and got to column IV and can't insert more columns. I
am saving the document in a compatability mode (.xls), could this be the

What is the maximum number of the columns?
Is the last column really named "IV"??

Excel 2007 allows 2 to the 12th (16384) columns, of which the last is headed
"XFD".
