JSON to Excel Converter via Webhook

This n8n workflow provides a simple, serverless API endpoint to transform JSON data into an Excel spreadsheet. It receives a JSON array through a POST request to the webhook, processes it into individual items, converts them to XLSX format, and responds with the binary file as a downloadable attachment. The filename defaults to 'Export.xlsx' but can be customized using the 'filename' query parameter (e.g., ?filename=report.xlsx).

Key benefits include eliminating the need for local software or libraries like Pandas or Excel—ideal for web apps, scripts, or integrations requiring quick data exports. It's lightweight with only 4 nodes, ensuring fast execution and low resource usage. Deploy it on n8n cloud or self-hosted for on-demand conversions.

Use cases: Export JSON from databases/APIs (e.g., CRM data, analytics results) to share with non-technical users; automate reporting in tools like Zapier or Make; batch process customer data for Excel analysis. With 43k+ views, it's proven reliable for file & document management tasks. Note: Update the webhook path before use.
