Apache POI Jar Conflict

Hi @surendra_Gollapudi ,
There is limited information in the question, but I’ll take a shot.
From a bit of googling , it appears that the apache POI needs a newer version of the commons.compress jar, have you confirmed that the apache poi and commons.compress are compatible?
Could you provide the version of IS that you are using?
Also provide a code sample of how you are trying to read the excel , and the full error stack trace.

You can refer this old thread - Error with get xlsx file if that helps.
