🧠 n8n Workflow: Delete HubSpot Contacts from an Uploaded Excel File

This n8n workflow allows you to upload an Excel file containing contact email addresses. It will check each one in HubSpot and delete the contact if it exists.

🔗 Workflow Overview

📥 1. Trigger via Webhook (POST)

The workflow starts when a .xlsx file is uploaded via an HTTP POST request to the webhook. This Excel file should contain a column with contact email addresses.

📄 2. Extract Data from Excel

The uploaded file is parsed, and its rows are converted into structured JSON items, making each email address available for further processing.

🧹 3. Normalize Data

The data is cleaned and normalized — for example, mapping column headers (e.g., emails) into a standard email field, ensuring consistent downstream logic.

🔁 4. Loop Through Contacts

Each row (contact) is processed individually using batch looping. This allows for fine-grained error handling and sequential processing.

🔎 5. Search for Contact in HubSpot

For each contact, a search query is made in HubSpot based on the email address. The workflow only fetches the first result (if any).

🧪 6. Check if Contact Exists

An IF condition checks whether the contact was found (i.e., if a HubSpot contact ID exists):

• ✅ Yes → proceed to delete the contact.
• ❌ No → skip deletion and continue to the next.

🗑️ 7. Delete Contact

If a contact exists, it is deleted from HubSpot using its internal contact ID.

🛠️ 8. Optional Placeholder for Post-Processing

A placeholder node named “Replace Me” is included for any custom logic you may want to add after the deletion step, such as:

• Logging
• Notifications
• Writing to external storage

✅ Use Cases

• Bulk delete old or bounced email addresses from HubSpot.
• Clean up contacts based on external suppression lists.
• Automate regular CRM hygiene processes.

💡 Suggested Enhancements

• ✍️ Log results to Google Sheets or a database
• 📬 Send completion report via email or Slack
• 🔁 Add retry logic for temporary API failures
• 🔍 Validate email format before making requests

📎 Requirements

• n8n (self-hosted or cloud)
• HubSpot App Token (set up in n8n credentials)
• Excel file (.xlsx) with a column for email

📦 Files

No external files are required. All logic is contained within the n8n workflow.

🚀 Getting Started

1. Deploy the workflow in n8n.
2. Copy the webhook URL and use it in your app or API client (like Postman).
3. Upload an Excel file containing contact emails via POST request.
4. Watch as it searches and deletes matches in HubSpot.
