In order to create an application where you can chat with your data, you first have to load your data into a format where it can be worked with. That’s where LangChain document loaders come into play. 

LangChain has over 80 different types of document loaders, and in this article, we’ll cover a few of the most important ones and get you comfortable with the concept in general. We will end the article with a practical tip that you can use to use them in an efficient way for your Large Language Model (LLM) applications.
