    Two ready-made SuperComponents simplify document preprocessing: MultiFileConverter, and DocumentPreProcessor.
    For example, if you have all extra dependencies for file conversion installed, you can run the following:
    ```python
        from haystack.super_components.converters import MultiFileConverter
        converter = MultiFileConverter()
        converter.run(sources=["test.txt", "test.pdf"], meta={})
    ```
