PostgreSQL Automate

PostgreSQL Automate streamlines data extraction by running queries on a PostgreSQL database, converting results into a spreadsheet format, and saving it as a binary file. This manual workflow simplifies data management, enabling quick access to essential product information like names and EANs, enhancing efficiency in data handling and storage.

Problem Solved

Problem Solved


This workflow automates the tedious process of querying a PostgreSQL database and exporting the results to a spreadsheet file. It eliminates manual data handling, reduces errors, and saves time by allowing users to generate reports with a single trigger. This is particularly useful for users who frequently need to analyze or share product data without having to manually run queries and format results.

Workflow Steps

Workflow Steps


1. Run Query Node: Executes a SQL query to retrieve the name and ean (European Article Number) from the product table in the PostgreSQL database. This step is crucial for gathering the necessary data.
2. Spreadsheet File Node: Converts the retrieved data into a spreadsheet format. This node prepares the data for easy consumption and analysis by converting raw data into a structured format.
3. Write Binary File Node: Saves the generated spreadsheet as a binary file named spreadsheet.xls. This final step ensures that the data is stored in a widely-used format, ready for distribution or further use.

Customization Guide

Customization Guide


- Modify SQL Query: Users can edit the query parameter in the Run Query node to retrieve different fields or data from other tables in the PostgreSQL database according to their needs.
- Change File Format: The fileName parameter in the Write Binary File node can be adjusted to change the output file name or format (e.g., .xlsx instead of .xls).
- Add More Nodes: Users can expand the workflow by adding additional nodes to process the data further, such as filtering or aggregating data before exporting.
- Integrate with Other Services: This workflow can be connected to other services or applications within n8n, allowing for more complex automation and data handling processes.
