# Default Data Loader
Use the Default Data Loader node to load binary data files or JSON data for vector stores or summarization.
On this page, you'll find a list of parameters the Default Data Loader node supports, and links to more resources.
!!! note "Examples and templates"
For usage examples and templates to help you get started, refer to n8n's [LangChain integrations](https://n8n.io/integrations/default-data-loader/){:target=_blank .external-link} page.
## Node parameters
* **Type of Data**: select **Binary** or **JSON**.
* **Data Format**: the file MIME type for binary data. Set to **Automatically Detect by MIME Type** if you want n8n to set the data format for you. If you set a specific data format and the incoming file MIME type doesn't match it, the node errors. If you use **Automatically Detect by MIME Type**, the node falls back to text format if it can't match the file MIME type to a supported data format.
## Node options
* **Metadata**: set the metadata that should accompany the document in the vector store. This is what you match to using the **Metadata Filter** option when retrieving data using the vector store nodes.
