I'm using Debian Linux and I want to convert a CSV file to an Excel XLS Spreadsheet file. The catdoc package includes the
xls2csv command that converts from XLS to CSV. However it doesn't do the reverse.
Since I just have a CSV file, I don't care about formatting or anything like that. I'm not worried if it only generates a very simple XLS file, and doesn't support the fancy new versions. Just so long as it's an XLS spreadsheet.
