@SalesDhorde I runned an example with the sample xlsx file and I got another exception, not NumberFormatException.

com.groupdocs.conversion.internal.c.a.w.UnsupportedFileFormatException: Unsupported file format: Unknown

So I need reproduce it first. Can you please attach the wole project to reproduce it?
