Effortlessly Import CSV Files to PostgreSQL with n8n
detail.loadingPreview
Streamline your data management by automating the import of CSV files directly into your PostgreSQL database. This n8n workflow simplifies the process, saving you time and reducing manual errors.
About This Workflow
This n8n workflow provides a robust solution for automating the ingestion of CSV data into a PostgreSQL database. It begins with a manual trigger to initiate the process, followed by a node to read your CSV file from a specified path. The data is then intelligently converted into a spreadsheet format, making it easy for the subsequent PostgreSQL node to parse and map. Finally, the workflow inserts or updates records in your chosen PostgreSQL table, ensuring your database stays up-to-date with minimal manual intervention. This is an essential tool for anyone dealing with regular data imports into PostgreSQL.
Key Features
- Automated CSV to PostgreSQL Import: Seamlessly transfer data from CSV files into your PostgreSQL database.
- Manual Trigger Initiation: Start the import process on demand with a single click.
- Flexible File Handling: Reads CSV files from a specified local path.
- Intelligent Data Conversion: Converts CSV data into a spreadsheet format for easy processing.
- Robust PostgreSQL Integration: Supports table and schema mapping for precise data insertion.
How To Use
- Trigger the Workflow: Click the 'execute' button on the manual trigger node to start the process.
- Specify CSV File Path: In the 'Read From File' node, update the
filePathparameter to point to your CSV file (e.g.,/tmp/my_data.csv). - Configure PostgreSQL Connection: In the 'Postgres' node, ensure your PostgreSQL credentials are set up correctly. Update the
tableandschemaparameters to match your target PostgreSQL table and schema. - Map Columns (if necessary): Review the
columnsparameter in the 'Postgres' node. The 'autoMapInputData' option will attempt to map columns automatically, but you can manually define mappings or specifymatchingColumnsfor upsert operations if needed.
