I have a Web site (PHP) that generates a CSV file (text/csv) with the following content:
ID;E-Mail_User;Name;Applikation;Rolle;Auftragsdatum;Administrator 522;user@do
CSV means C omma S eparated V alues, which is not what your document contains.
Those are semicolons.
If possible, change the PHP code to generate this instead (which is actually CSV):
ID,E-Mail_User,Name,Applikation,Rolle,Auftragsdatum,Administrator
522,user@domain,WXDUILAS,ABCD,XYZ,2009-03-04 05:00:09,user@domain
...or specify ;
as the delimiter using the Text Import
dialog.
