Hi Manoj,

I need to comma seperated values in one cell for the same name .
Example: Name of student in one column and the the corresponding column cell should have all the subjects opted by the student . The list of students and the subjects will be from select query.

But sir in a practical case, each file will have records of comma separated values right
.. so in that case how will this work ? We cannot have csv.111 attributes etc... Extracted if file is long.
