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: [email protected]
ReportedBy: [email protected]

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.
