No, HSSF is an api that you use to read/write files, it is not a way to 'automate' Excel itself as I am guessing you want to do.
Why not look at Excel itself for this process? Remember that it is possible to 'program' Excel - VBA I know which is not nice. Failing that, the language Python has a windows API that may allow you to control Excel programatically (assuming you are running on Windows of course) and there are ways to control Excel from Java (OLE control of an application is possible but again only under Windows). Finally, there may be a commercial product that allows you this sort of control. --- On Tue, 7/22/08, Peters,Shawn <[EMAIL PROTECTED]> wrote: From: Peters,Shawn <[EMAIL PROTECTED]> Subject: Spreadsheet w/o writing file out To: [email protected] Date: Tuesday, July 22, 2008, 1:51 PM I am currently looking at POI as a solution for opening some CSV files into Microsoft Excel. What we want to do is to hand off the CSV data (pulled from a database as a blob) to our newly created spreadsheet and then open the Excel application all in memory without writing the spreadsheet out to the file system. Is this possible with POI or do I need to use the file system?
