CVS creation

Hi, I have logfiles since 2009 but I have activated the option to create the LG* CVS only on 2013. It exists a way to convert my old logfiles into CSV files?
The reason is that I’m running meteotemplate that accepts WD CSV in order to upload bulk data
Thanks
Giordolo

it will also accept the normal logfile I thought if you set to be space delimited?
