Should create one .csv for each table CREATEd in a MySQL export. Result might be dependent on export parameters, this has been tested for only one particular export file.

mysql2csv.awk

#!/usr/bin/awk -f

BEGIN { RS=";\n"; }
{
        if ( $1 == "CREATE" ) {
                fn = substr($3,2,length($3)-2) ".csv";
                print fn > fn;
        }
        if ( $1 == "INSERT" ) {
                iv = index($0,"(")+1;
                print substr($0,iv,length($0)-iv) >> fn;
        }
