You could try using an Excel VB script to do it. I'm considering doing the same thing. We receive reports from vendors in Excel spreadsheet formats currently. The users are now forced to save the document as a CSV file and then call up an Oracle Forms page and enter the CSV filename. I use the utility TEXT_IO to read the file in its comma delimited form. For me, this process is highly dependant on the user correctly saving the file. This causes me to perform very specific data format checking in my PL scripts. To alleviate this, I'm considering using the VB script as I mentioned. I haven't investigated it, its just an idea. Of course it'll be dependent on whether I can connect to the Oracle DB within the VB script in Excel.
Good luck.
