n8n Tally + OpenAI Discord App Review Workflow to Google Sheets

Automate Discord application reviews with Tally, OpenAI, and Google Sheets

This n8n workflow automatically reviews new Tally form submissions for your Discord community using OpenAI, then posts a decision to the right Discord channel and logs an audit trail in Google Sheets.

What this workflow does

• Triggers on new Tally submissions: Starts whenever someone submits an application form through Tally Forms.
• Extracts key applicant fields: Normalizes the data into a consistent structure (e.g., name, email, grade, experience, and comment).
• Validates required inputs: Checks that required fields like email and application content exist; if missing, it sends a Discord error notification.
• Uses OpenAI for structured review: Sends the application text to an OpenAI chat model to extract a structured result including status, reason, confidence, risk, and a short Japanese summary.
• Routes by AI status: Uses conditional logic to post the formatted review message to the matching Discord channel for Approved, Needs Review, Rejected, or Unknown.
• Logs to Google Sheets: Appends applicant details plus the AI review output into a spreadsheet tab for auditing.

Use cases

• Reviewing Discord community applications submitted via Tally with consistent AI-assisted decisions.
• Reducing manual moderation by routing applicants to Approved vs Needs Review channels based on OpenAI outputs.
• Maintaining compliance-friendly records by storing review decisions and reasoning in Google Sheets.
