    Parses CSVs using the separator detection from Pandas `read_csv`function.
    If special parameters are required, use the `pandas_config` dict.

    Args:
        concat_rows (bool): whether to concatenate all rows into one document.
            If set to False, a Document will be created for each row.
            True by default.

        col_joiner (str): Separator to use for joining cols per row.
            Set to ", " by default.

        row_joiner (str): Separator to use for joining each row.
            Only used when `concat_rows=True`.
            Set to "\n" by default.

        pandas_config (dict): Options for the `pandas.read_csv` function call.
            Refer to https://pandas.pydata.org/docs/reference/api/pandas.read_csv.html
            for more information.
            Set to empty dict by default, this means pandas will try to figure
            out the separators, table head, etc. on its own.

    Parses Excel files using Pandas' `read_excel` function, but formats
    each row to include the header name, for example: "name: joao, position: analyst".
    The first row (header) is not included in the generated documents.

    Args:
        concat_rows (bool): Determines whether to concatenate all rows into one document.
            If set to False, one Document is created for each row.
            Defaults to True.
        sheet_name (str | int | None): Defaults to None, meaning all sheets.
            Alternatively, pass a string or an integer to specify the sheet to be read.
        field_separator (str): Character or string to separate each field. Default: ", ".
        key_value_separator (str): Character or string to separate the key from the value. Default: ": ".
        pandas_config (dict): Options for the `pandas.read_excel` function call.
            Refer to https://pandas.pydata.org/docs/reference/api/pandas.read_excel.html
            for more details.
            Defaults to an empty dictionary.
