First thanks for your answer BUT..
i take the output of export (
'mes livres.csv' see 'mes livres.rar' attached)
i make a new xsl file (
classeur1.xlsx) and import 'mes livres.csv'
i arrange xsl file : permutation of columns ( see classeur1.rar)
how can i produce
the same layout as 'mes livres.csv' from 'classeur1.xls' for importing in collectorz ???
