Hi,

Here is a quick hack that converts csv to commalist values.
Perhaps it helpful for someone. Documentation blurb:


  This module parses CSV data (somewhat) safely. After

  \def\dataline{a,,\j,a",a\j a",t{f},",","""","a""b"}
  \convertcsvdata\dataline\to \myascii
  \message{\meaning\myascii}

  output is:

  macro:->{a},{},{\j },{a"},{a\j a"},{t{f}},{,},{"},{a"b}

  The result is detokenized, like would be with \type{\convertargument}.
  Therefore, you will need to run \type{\scantokens} over the list
  items if the CVS data was actually \TeX{} code.

Cheers,
Taco
