Workflow Name

Export Webhook Data to Excel File

Key Features and Highlights

This workflow receives data from external POST requests, processes nested list data by splitting it accordingly, and automatically generates an Excel (.xlsx) spreadsheet file. The generated file is then returned directly to the requester via the Webhook response, enabling fast data export and download.

Core Problem Addressed

It solves the challenge of quickly converting complex list data received from APIs or external systems into structured, easy-to-view, and analyzable Excel files, eliminating the tedious manual data organization and format conversion process.

Use Cases

  • Developers or system integrators converting system-generated JSON data into Excel format for easier review and archiving by business users;
  • Business scenarios requiring automated report or data snapshot exports via API;
  • Data collection platforms quickly exporting collected results to users or other systems.

Main Workflow Steps

  1. Webhook Receives Request: Listens on a specified POST endpoint and accepts incoming JSON data;
  2. Item Lists Data Splitting: Extracts nested list data from the request body and processes each item individually;
  3. Generate Spreadsheet File: Converts the split data into an Excel spreadsheet file;
  4. Respond to Webhook Request: Returns the generated Excel file as an attachment, supporting custom file naming.

Involved Systems or Services

  • Webhook (for receiving and responding to HTTP requests)
  • n8n’s built-in Item Lists node (for data splitting)
  • Spreadsheet File node (for Excel file generation)

Target Users and Value

  • Developers and automation engineers who need to quickly convert API data into Excel format;
  • Business analysts and managers who benefit from automatically generated Excel reports for rapid data insights;
  • Enterprises or teams aiming to enhance efficiency and reduce manual errors by exporting structured data through simple interfaces.
