xls to text converter
Anyone know of a free xls to text converter that can be run from the unix command line?
There is also the package catdoc (Ubuntu link) that includes a xls2csv utility.
Your question reminded me of anti-word. I looked up and found anti-excel. I have never used it, so I can't vouch for how well it work or whether it makes achievable the task you have at hand. Also, I remember using a utility called 'sc' on linux to created spreadsheets on the console---though, I do not know whether it is capable of interpreting XLS files.
I think gnumeric is better to convert document to csv http://xmodulo.com/2012/06/how-to-convert-xlsx-files-to-xls-or-csv.html
