python
from haystack_integrations.components.converters.opendataloader_pdf import OpenDataLoaderConverter

converter = OpenDataLoaderConverter(output_format="markdown")
result = converter.run(sources=["report.pdf"], meta={"source": "annual-report"})

documents = result["documents"]
print(documents[0].content)

    *,
    output_format: OutputFormat = "markdown",
    convert_kwargs: dict[str, Any] | None = None
) -> None
