The DocxLoader allows you to extract text data from Microsoft Word documents. It supports both the modern .docx format and the legacy .doc format. Depending on the file type, additional dependencies are required.

​
Setup

To use DocxLoader, you’ll need the @langchain/community integration along with either mammoth or word-extractor package:
  • mammoth: For processing .docx files.
  • word-extractor: For handling .doc files.

​
Installation

​
For .docx Files

npm
npm install @langchain/community @langchain/core mammoth

​
For .doc Files

npm
npm install @langchain/community @langchain/core word-extractor

​
Usage

​
Loading .docx Files

For .docx files, there is no need to explicitly specify any parameters when initializing the loader: 
import { DocxLoader } from "@langchain/community/document_loaders/fs/docx";

const loader = new DocxLoader(
  "src/document_loaders/tests/example_data/attention.docx"
);

const docs = await loader.load();

​
Loading .doc Files

For .doc files, you must explicitly specify the type as doc when initializing the loader: 
import { DocxLoader } from "@langchain/community/document_loaders/fs/docx";

const loader = new DocxLoader(
  "src/document_loaders/tests/example_data/attention.doc",
  {
    type: "doc",
  }
);

const docs = await loader.load();
