Hi Karl,
Thank you for your reply. I am still having a question that seeks some suggestions.
In the link of "Batch-Import list data into pdf form", I can understand that in the code part, it is to create a temporary document to store the data from txt file. But I can not find how to import that existed pdf "sign-in sheet" and how to generate that pdf form to be ready to download. I mean, how to get this generated pdf "sign-in sheet", I am a little bit confused because I am still a beginner for javascript currently.
Really appreciate for your help.
