I’ve been trying to figure out the best way to work with uploaded documents in my LangGraph setup. Specifically, I need to process Excel spreadsheets and PDF documents that users upload, extract data from them, and run analysis without keeping the files permanently stored.
I’m having trouble finding the right approach for this. The files are just temporary inputs for analysis purposes, so I don’t need any long-term storage solution. I’ve looked through the documentation but I’m still confused about the proper workflow.
Has anyone dealt with similar file processing requirements? What’s the recommended way to handle document ingestion and analysis in LangGraph? Any code examples or guidance would be really helpful.
