Default Data Loader node

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.

Node parameters

Text Splitting: Choose from:
- Simple: Uses the Recursive Character Text Splitter with a chunk size of 1000 and an overlap of 200.
- Custom: Allows you to connect a text splitter of your choice.
Type of Data: Select Binary or JSON.
Mode: Choose from:
- Load All Input Data: Use all the node's input data.
- Load Specific Data: Use expressions to define the data you want to load. You can add text as well as expressions. This means you can create a custom document from a mix of text and expressions.
Data Format: Displays when you set Type of Data to Binary. Select the file MIME type for your 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.

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.
