) #### Description This PR adds the option to specify additional metadata columns in the CSVLoader beyond just `Source`. The current CSV loader includes all columns in `page_content` and if we want to have columns specified for `page_content` and `metadata` we have to do something like the below.: ``` csv = pd.read_csv( "path_to_csv" ).to_dict("records") documents = [ Document( page_content=doc["content"], metadata={ "last_modified_by": doc["last_modified_by"], "point_of_contact": doc["point_of_contact"], } ) for doc in csv ] ``` #### Usage Example Usage: ``` csv_test = CSVLoader( file_path="path_to_csv", metadata_columns=["last_modified_by", "point_of_contact"] ) ``` Example CSV: ``` content, last_modified_by, point_of_contact "hello world", "Person A", "Person B" ``` Example Result: ``` Document { page_content: "hello world" metadata: { row: '0', source: 'path_to_csv', last_modified_by: 'Person A', point_of_contact: 'Person B', } ``` --------- Co-authored-by: Ben Chello <bchello@dropbox.com> Co-authored-by: Bagatur <baskaryan@gmail.com>
