Form Submission to Google Sheets

1 newbie
Webhooks Google Sheets Data Validation

Capture form submissions via webhook and append validated data to Google Sheets. Master webhook handling, data validation, and spreadsheet operations.

Your Challenge

Core Functionality

Your workflow must:

  • Set up Webhook Trigger node to receive form submission data
  • Parse incoming webhook payload (JSON format)
  • Extract form fields: name, email, message, timestamp
  • Validate email format and required fields are present
  • Connect to Google Sheets using credentials
  • Append new row to spreadsheet with form data
  • Return success response to webhook caller (HTTP 200)

Edge Cases

Your workflow should handle:

  • Handle submissions with missing optional fields
  • Deal with special characters in form data (quotes, commas, line breaks)
  • Process very long text inputs (truncate or handle appropriately)

Bonus Challenges (Optional)

Take it further by:

  • Send confirmation email to submitter after successful save
  • Add data enrichment (geolocation, timestamp formatting, calculated fields)
  • Implement spam detection (honeypot fields, rate limiting)
  • Create summary statistics dashboard from accumulated data
  • Add Slack/Discord notification for new submissions
  • Support file uploads and save attachment URLs

Tips & Hints

  • Use the Webhook Trigger node in "POST" mode to receive form data
  • The Google Sheets node requires OAuth2 authentication setup
  • Test webhook with tools like Postman or curl before connecting real forms
  • Use the Set node to restructure data before sending to Google Sheets
  • The Function node can validate email formats using regex
  • Consider using the Respond to Webhook node to send immediate confirmation
