# Document loaders

Document loaders provide a **standard interface** for reading data from different sources (such as Slack, Notion, or Google Drive) into LangChain's [Document](https://reference.langchain.com/javascript/classes/_langchain_core.documents.Document.html) format.
This ensures that data can be handled consistently regardless of the source.

All document loaders implement the [BaseLoader](https://reference.langchain.com/javascript/classes/_langchain_core.document_loaders_base.BaseDocumentLoader.html) interface.

## Interface

Each document loader may define its own parameters, but they share a common API:

* `load()`: Loads all documents at once.
* `loadAndSplit()`: Loads all documents at once and splits them into smaller documents.

```typescript theme={null}
import { CSVLoader } from "@langchain/community/document_loaders/fs/csv";

const loader = new CSVLoader(
  ...  // <-- Integration specific parameters here
);
const data = await loader.load();
```

## By category

LangChain.js categorizes document loaders in two different ways:

* [File loaders](/oss/javascript/integrations/document_loaders/file_loaders/), which load data into LangChain formats from your local filesystem.
* [Web loaders](/oss/javascript/integrations/document_loaders/web_loaders/), which load data from remote sources.
