Bonjour,
Voici un essai :
chemin = thisworkbook.path & "\nouveaufichier.xslx"
workbooks.add
thisworkbook.sheets("Feuil1").cells.copy activeworkbook.sheets(1).cells
activeworkbook.close true, chemin
Sinon, il est probablement possible de faire :
chemin = thisworkbook.path & "\nouveaufichier.xslx"
sheets("Feuil1").copy
activeworkbook.saveas chemin, xlOpenXMLWorkbook
activeworkbook.close false
Cdlt,
