In PB 12.5 we had a problem with the saveas() function of a datawindow in xlsx! format ( our regional settings are french, so the comma is the decimal separator). When opening the generated xlsx file, Excel complains about a problem, proposes to repair, and only after that our customers can see the contents of the Excel file ( this process is not acceptable for the end-users)
This bug was fixed in EBF 20488: 12.5.1 (4595) ( see below) but the bug is there again in PB15 BETA
20488 695756 Excel12! format
results in unreadable content for
a DataWindow datetime column, when the regional
settings are set to have a comma as decimal
separator.
