Hi Ketal,
Thank you for using Essential XlsIO.
It is not directly possible to convert a Excel file to PDF, but a work around will be to first convert Excel file to image and then adding the image to pdf file.
Please follow the link below to find the sample application to convert Excel to PDF.

Please let me know if you have any further questions.

Vijesh
