Keeping an online store catalog in sync with n8n + a local LLM (Ollama)

Short summary

A developer automated online store catalog syncing using n8n (workflows) and Ollama (local LLM) to eliminate manual price and stock monitoring. The system normalizes messy supplier data with the LLM, matches items to store listings with confidence scoring, auto-updates matches, and flags exceptions for review. Key insight: LLMs excel at fuzzy data cleaning but should never be sole decision-makers for pricing or inventory—always add deterministic validation.

• •Uses n8n + local Ollama LLM for scheduled catalog syncing
• •Normalizes messy supplier data and auto-matches to store items
• •Flags exceptions instead of making risky decisions with LLM alone
