Can n8n handle ETL tasks for messy data and complex cleaning needs?

n8n isn’t a dedicated ETL platform like some specialized tools, but it does provide a range of built-in nodes that help you build ELT/ETL workflows through automation. For example, you can use nodes to extract data from JSON APIs, read Sheets/Excel files, and even scrape web data. For transforming and cleaning data, n8n provides transformation nodes such as:

• Aggregate – Group data into individual items
• Limit – Remove items beyond a defined maximum
• Remove Duplicates – Delete identical items across fields
• Sort – Organize lists in a specific order
• Split Out – Separate a list within a single item into multiple items
• Summarize – Aggregate items together (similar to pivot tables)

These nodes let you mold incoming, often “messy” data into formats that other nodes in your workflow can process effectively.

If your ETL needs require more extensive data cleaning or transformation than what these nodes offer, you might consider using additional dedicated ETL tools. Popular recommendations include:

• Apache NiFi – A robust data integration tool for routing and transformation
• Talend Open Studio – A comprehensive ETL solution with powerful data cleaning capabilities
• Pentaho Data Integration (Kettle) – Known for extensive transformation and data processing features

In summary, n8n can be a good option if you prefer a node-based, low-code environment for automating tasks and building pipelines, but for very complex or heavy-duty ETL scenarios with extensive cleaning requirements, one of the dedicated ETL tools might be more appropriate.
