Hi!
exporter example

1 at end of gluon/sqlhtml.py
class ExporterXLS(ExportClass):
label = 'XLS'

import xlwt, cStringIO
if len(self.rows) == 0:
return 'empty rows-table'

self.rows.colnames ]
(table_name, _)= rows_colnames[0].split('.')
book = xlwt.Workbook()
sheet = book.add_sheet(table_name)
first_xls_row= 0
# rows.db.licence.fld2.represent(row.fld2,3)
def list2xls(row_num,line_list):

sheet.write(row_num, col_num, value)
