What Are Data Tables in n8n
Data Tables are built-in, spreadsheet-like collections that store rows and columns of information inside n8n. Think of them as lightweight databases that are secure, fast, and easy to query within any workflow.
Each Data Table has its own schema, permission controls, and API access path — meaning teams can treat them like embedded databases for automations.
Why Use Data Tables
- Eliminate external database dependencies for smaller automations
- Store structured information between workflow runs
- Link AI outputs or webhooks to reusable datasets
- Manage user inputs, leads, or logs easily inside n8n
- Query and update data dynamically during workflow execution
How to Create and Use n8n Data Tables
- Open n8n and navigate to the Data Tables tab.
- Click New Table and define the column structure (for example: name, email, status).
- Add or import sample rows manually, or let a workflow populate them.
- Inside a workflow, use the Data Table node to read, write, or delete rows.
- Connect results to other nodes like Gmail, Notion, or AI models for processing.
Example Use Cases
- Lead Management: Store captured leads from a form webhook and update their status after email verification.
- AI Output Tracking: Record GPT or DeepSeek responses for future review or fine-tuning.
- CRM Sync Logs: Track CRM API events, failed updates, or webhook calls.
- Team Reporting: Create a shared table for daily performance metrics synced to Google Sheets.
- Chatbot Memory: Save user messages and context for consistent AI responses over time.
Data Tables vs External Databases
| Feature | Data Tables | External DB (MySQL, Airtable, etc.) |
|---|---|---|
| Setup | Instant inside n8n | Requires external config |
| Performance | Optimized for small to medium data | Scalable for large enterprise use |
| Ease of use | Visual and simple | Requires SQL or API familiarity |
| Integration | Seamless inside workflows | Needs custom connection setup |
Verdict
The n8n Data Tables feature bridges the gap between automation and data management. It’s perfect for creators who want a fast, internal data layer without relying on third-party tools. For small to medium-scale automations, Data Tables offer a powerful way to store and query information natively.
