It's hard to make tables in LaTeX especially if some columns are calculated. This Excel-To-LaTeX converter exports the current selection as a LaTeX file which can be included via the \input command in an existing LaTeX document. Nearly all formatting is supported (bold, italic, border lines, multicolumn cells, …). Works with Excel up to Excel 2010.
