Users who choose either the Excel 2003 or CSV (comma separated value) file types for use in a spreadsheet application should be aware that Excel has a limit of 256 columns. If a downloaded file exceeds 256 columns, it may not open correctly in the spreadsheet program.

Also note that it is often the case that Excel tries to automatically format some types of data so it is possible that the format shown by the Excel software may not be precisely what is in the data file.
