Description Jan Lolling 2023-10-09 10:58:02 UTC 
You cannot append rows into SXSSF workbooks. The method the retrieve the number of already existing rows returns only the current created rows and not the rows already exists if the workbook is read from a file.
I have already solved this bug and would like to contribute a patch to the project. 
The necssary changes affects only the class org.apache.poi.xssf.streaming.SXSSFSheet
