Postgres to Excel (XLS) n8n Workflow: Export Spreadsheet File

Export PostgreSQL data to an Excel (XLS) file with this n8n workflow

This Postgres to Excel (XLS) n8n workflow reads data from your Postgres database, converts it into an Excel spreadsheet (XLS), and saves the resulting file to disk—perfect for reliable, repeatable reporting exports.

What this workflow does

Designed for straightforward data export, the workflow follows these steps:

• Read data from Postgres using the PostgreSQL node.
• Convert the retrieved results to XLS, preparing them as a spreadsheet file.
• Write the spreadsheet to disk by using a file output approach (write binary file) so you can download or use the generated Excel file downstream.

Use cases

• Weekly or daily reporting: automatically export query results from Postgres into an Excel file for business stakeholders.
• Data reconciliation: generate XLS snapshots of production data to compare with external sources or internal audits.
• SaaS operations: create export artifacts for support, migration prep, or customer-facing datasets.
• Automation engineering: use as a building block for larger n8n pipelines that distribute the exported XLS.

Technical details

• Integrations / nodes: postgres, spreadsheet file, write binary file
• Output format: Excel (XLS) spreadsheet
• Storage: saves the generated XLS file to disk

If you need a clean Postgres → Excel (XLS) export inside n8n automation, this workflow gives you a focused, practical solution that’s easy to run and integrate into your reporting processes.
