For more specific information, please refer to the following FAQ: Can I import Excel Row Height (16.5) into AutoCAD/MicroStation exactly?
My problem is that in some, but not all, cases when the text in a cell wraps, the cell size in the anonymous block produced by your program does not “grow” sufficiently to maintain the look of the spreadsheet. The text then overlaps the text in adjacent cells. You can adjust the column width a little manually, so that the cells can fill the text. AutoTable imports Excel spreadsheet into AutoCAD by 1:1, i.e. the point size from Excel to an equivalent size in AutoCAD units. But with regard to text, AutoCAD and Excel have different arithmetics to display the same truetype font.
