n8n Workflow: AI Write Word Docs from Google Sheets (Groq + Pandoc)

Turn Google Sheets topics into Word documents automatically (Groq + Pandoc)

This n8n workflow reads article topics and reference links from your Google Sheets, uses a Groq-powered LangChain agent to write a 1500+ word Markdown article, converts it to a .docx with Pandoc on your machine, and uploads the finished Word files to Google Drive.

What this workflow does

• Manual trigger: You start the workflow when you’re ready to generate documents.
• Reads your Google Sheets rows: It pulls the topic, reference URLs (e.g., AHREFLINKS), and an article identifier (e.g., an ART-001 value used for filenames).
• Generates long-form content: For each row, it sends the topic and links to a LangChain agent backed by the Groq Chat Model to produce a 1500+ word Markdown article.
• Saves locally as Markdown: The workflow writes the generated .md file to your configured local folder using the article ID as the filename.
• Converts Markdown to Word: It runs a Pandoc command on the same machine to convert the local .md into .docx.
• Uploads to Google Drive: Finally, it loads the converted Word document from local storage and uploads it to the selected Google Drive folder.

Use cases

• Content teams: bulk-generate article drafts from a Google Sheet and deliver them as Word documents for editing.
• SaaS operators: create repeatable doc workflows for internal knowledge bases using topics + references stored in Sheets.
• Automation engineers: a practical n8n example combining LLM writing (Groq via LangChain) with local file conversion (Pandoc) and Drive publishing.

Technical details

• Integrations/credentials: Google Sheets, Google Drive, and the Groq API for the LangChain agent.
• Core n8n nodes: Manual trigger, Set, Sticky Note, Google Sheets, Convert to File, Google Drive.
• Local requirements: n8n must run on a machine that can write to a local directory (e.g., D:\n8n-files\), with Pandoc installed and available on the system PATH.
