[docs]class UnstructuredPowerPointLoader(UnstructuredFileLoader):
    """Load `Microsoft PowerPoint` files using `Unstructured`.
    Works with both .ppt and .pptx files.
    You can run the loader in one of two modes: "single" and "elements".
    If you use "single" mode, the document will be returned as a single
    langchain Document object. If you use "elements" mode, the unstructured
    library will split the document into elements such as Title and NarrativeText.
    You can pass in additional unstructured kwargs after mode to apply
    different unstructured settings.
    Examples
    --------
    from langchain.document_loaders import UnstructuredPowerPointLoader
    loader = UnstructuredPowerPointLoader(
        "example.pptx", mode="elements", strategy="fast",
    )
    docs = loader.load()
