This example goes over how to load data from multiple file paths. The second argument is a map of file extensions to loader factories. Each file will be passed to the matching loader, and the resulting documents will be concatenated together.
Example files:
src/document_loaders/example_data/example/
├── example.txt
└── example.csv
src/document_loaders/example_data/example2/
├── example.json
└── example.jsonl
