Encode JSON to Base64 String in n8n
This example workflow demonstrates how to convert a JSON object into a base64-encoded string using n8n’s built-in file processing capabilities. This is a common requirement when working with APIs, webhooks, or SaaS integrations that expect payloads to be base64-encoded.
> Tip: The three green-highlighted nodes (Stringify → Convert to File → Extract from File) can be wrapped in a Subworkflow to create a reusable Base64 encoder in your own projects.
---
🔧 Requirements - Any running n8n instance (local or cloud) - No credentials or external services required
---
What This Workflow Does 1. Generates example JSON data 2. Converts the JSON to a string 3. Saves the string as a binary file 4. Extracts the file’s contents as a base64 string 5. Outputs the base64 string on the final node
