OpenAI Assistant Citation Formatter for File Retrieval RAG

This n8n workflow solves a common annoyance with OpenAI Assistants that use file search: messy, hard-to-read citations. It connects to an OpenAI Assistant equipped with a vector store, retrieves the full thread content, and parses out every message, citation, and referenced file, replacing generic citation markers with the actual file names. The final output can also be converted from Markdown to HTML for clean display. It's a practical fix for developers building document Q&A assistants who want professional, readable source citations instead of raw file IDs and odd characters in the response.
