Natural Language to SQL Converter for Google Sheets with GPT-4o

This n8n workflow creates an intelligent system that converts everyday language questions into precise Google Sheets SQL queries powered by OpenAI's GPT-4o model. It automatically maps column names to letters (A, B, C), builds formatted query URLs, and executes them through HTTP requests to fetch live data, bypassing API limits and enabling real-time insights.

Key benefits include effortless data querying for non-technical users, conversation memory for follow-up questions, and efficient handling of large datasets. It saves hours of manual SQL writing, reduces errors, and integrates seamlessly with existing Sheets, making it ideal for teams needing quick analytics without developers.

Use cases span business intelligence like sales reporting ('What were last month's top products?'), content analysis in media/entertainment ('Which videos got most views?'), and monetization tracking ('Summarize revenue by category'). Perfect for marketers, analysts, and content creators monetizing data-driven decisions.

Features structured output parsing, dual GPT models (GPT-4o for queries, GPT-4.1 Mini for formatting), Google Sheets schema extraction, memory buffer for context, and chat trigger for webhook conversations. Setup is straightforward with OpenAI and Google credentials.
