How can I make a chatbot that can get a user specific input like text and number and extract the information in the form of a text file?

I tried adding names and extracting entities but when I use a name that’s not predefined as an entity it does not work for me. I am also not that good at programming, so how can we use the chatbot to extract user information like name and phone number?
