tool to convert dBase (dbf) files

Hello,
I have a large dBase file from a GRASS vector wich I want to process as an ascii
file.

The number of records surpasses the number of maximum records in OOo Calc or
Gnumeric.

Is there a tool which can convert a dBase file into a ASCII or CSV file?

I found a Freeware tool from a German website:
WinDBF32 Datenbank Editor - http://www.buchenwald.de/software/index.html

Is there something like this as FOSS?

Or does anyone know whether I can directly export a attribute table from a GRASS
vector to ascii?

Thanks in advance and kind regards,
Tim
