Excel generated from CSV is not importing data in table

Hi All, 

I am working on a use case where i need to first convert CSV to excel then import converted excel with extra column to a staging table. 

Reason to use import excel to database intend of directly using csv to database is i need to dynamically add process instance id in staging table. I didn't find any option to achieve same in CSV to Database. 

CSV to excel is working fine. I am able to generate XLSX file and passing it to import excel to database. My process is getting completed successfully but i don't see data in staging table. 

I tried converting csv to xlsx in my local machine and used locally converted xlsx in process model, it worked but same when i am trying to achieve from CSV to excel smart service generated excel, data is not getting imported. I don't have auto generated column in my XLSX file.

Please advice what can be done resolve this issue. 

Thanks in advance for your help.
