Andreas Nef Thanks for posting your question in Microsoft Q&A. As mentioned by Bruno Lucas, there are no supported bindings available for SharePoint in Azure Functions. You can use PnP Framework or CSOM to connect to SharePoint and process the output based on your need.
Here are some references that would be helpful:
PnP V4 .NET 6 - https://pnp.github.io/pnpcore/demos/Demo.AzureFunction.OutOfProcess.AppOnly/readme.html
PnP Code samples - https://github.com/pnp/pnpcore/tree/dev/samples
CSOM discussion thread: Use CSOM instead of PnP core to interact with SharePoint online inside my Azure function, detailed steps: https://learn.microsoft.com/en-us/answers/questions/1167689/what-i-need-to-do-to-replace-pnp-core-services-wit
Alternatively, if you can use Logic Apps, it has SharePoint connector to connect to SharePoint and manage documents/list items and review known issues and limitations. I hope this helps with your question and let us know if you have any other questions or face issues.
