Use **Pandas Load CSV** node to load a CSV, or **Pandas Load CSV With Index** node if the CSV contains an index column. These nodes assume that the file is encoded in utf-8. If the file is not encoded in utf-8, use **Pandas Load CSV With Encoding** to specify the encoding of the file. This is necessary if the data was collected before utf-8 encoding became popular.
