Subject DO NOT REPLY [Bug 51634] New: xssf.streaming with existing xlsx files/templates
Date Mon, 08 Aug 2011 19:55:01 GMT

             Bug #: 51634
           Summary: xssf.streaming with existing xlsx files/templates
           Product: POI
           Version: 3.8-dev
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: SXSSF
        AssignedTo: dev@poi.apache.org
        ReportedBy: vladt@sonatype.com

Created attachment 27361

The implementation

Currently, the xssf.streaming can be used only to create new xlsx documents,
not to open and change existing xlsx documents.

It would be nice to be able to open an existing xlsx document (as a template)
and add to it (rows to existing sheets, new sheets, etc) while taking advantage
of the very low memory reqs for xssf.streaming.

The attached patch adds this functionality.
