Process Contact Forms: Validate & Store in MongoDB

This n8n workflow efficiently handles contact form submissions by capturing user inputs like name, last name, email, and phone number. It includes a robust validation layer that removes suspicious characters to prevent SQL or script injections, checks phone number formats, and flags invalid entries to avoid database pollution. Data is then formatted into snake_case fields (e.g., first_name, last_name) for consistency before insertion into MongoDB Atlas.

The workflow starts with a Form Submission node as the entry point, followed by a Code node for validation, an Edit Fields node for normalization, and a MongoDB node for secure storage using a connection URI. This setup ensures data integrity and security without manual intervention.

Benefits include time savings on manual data entry, enhanced security against malicious inputs, and scalable storage for growing form submissions. It's ideal for websites, landing pages, or apps needing reliable lead capture.

Use cases: E-commerce contact forms, customer support inquiries, newsletter signups, or any web form requiring validated storage in MongoDB. Easily customizable for additional fields or integrations.
