i am wondering that what is the best way to insert massive data into an existing excel file, more performance perspective.
the file is read from BDS , and we want to insert data into it .
the way i can think of is
1. OLE AUTOMATION
i think performance will be a big problem
2. Office integration
i am not sure it's facing the same performance issue ?
3 . XXL_SIMPLE_API/FULL_API
I am not sure whether they can insert data into an existing excel file?
could you please give me some advices?
