How to extract data from .pdf in Office 365

I am designing an Office 365 web application and need guidance if this is possible or not. I have not worked with an Office 365 application in this capacity and yet that is the tech I am given by management. First, here are the requirements-

1. Within an Office 365 presented in web, provide a list of existing pdf documents with fillable form fields
2. Allow a user to click on a form, present the form in the UI, and allow the user to fill in the form fields
3. After the user fills in the form, provide a submit button
4. Once the submit button is clicked, data should be extracted from the pdf and saved to Office 365 tables.

I have not worked with an Office 365 web app. Not sure what can or can't be done to achieve the requirements.

I know this is a little vague, but I am only asking of how this could be done at a high level. Can it be done using only Office 365? Do I need to use a UI language such as Angular? Are there libraries I will need to import? Links to tutorial on similar functionality? Any help is greatly appreciated!
