list item has to show as a pdf

This might get you started: Nintex Workflow/Forms to PDF - Vadim Tabakman

A company called "Muhimbi" makes some workflow actions that convert stuff into PDF.  You should be able to google them.

Thanks,

Hi,

You can Create the MS-Word Template and then Lookup the List items in that Template and then convert it to PDF.

The article should be a good starting point : Inserting SharePoint List data into a PDF document using a workflow 

I am using Muhimbi PDF Converter for SharePoint Online / Office 365 - Home to automate the entire process.

I hope it helps :-)
