Can you post a minimal set of code which reproduces this? It seems to be happening during writing and it might be related to what you actually do before in your code.

I have loaded the workbook in the workbook object and sheet in xssf sheet. 
Before writing the data I have read the data from it then write the data by using same workbook and sheet object.

Need code. Can't help otherwise.

Comment 4 Dominik Stadler 2018-06-28 15:22:36 UTC

We cannot do much without code or sample documents, so this is bug-report is INVALID until we receive more information.
