Automate File Creation and Manipulation with n8n
detail.loadingPreview
Streamline your data workflows by automating the creation and transformation of binary files. This n8n workflow snippet demonstrates how to generate example data, convert it into a binary format, and save it as a file, enabling seamless integration and processing.
About This Workflow
This n8n workflow showcases a powerful combination of nodes to automate file generation and manipulation. It begins by creating sample JSON data using a function node. This data is then transformed into a binary representation, suitable for storage or further processing, also within a function node. Finally, the Write Binary File node takes this binary data and saves it to a specified file, in this case, test.json. This entire process can be triggered automatically, eliminating manual steps and ensuring data consistency. It's an essential building block for any automated data pipeline, allowing you to manage and utilize binary assets programmatically.
Key Features
- Automated Data Generation: Easily create sample or dynamic data for testing and integration.
- Binary Data Transformation: Convert structured data into a binary format for efficient storage or transfer.
- Direct File Writing: Save generated binary data directly to files within your workflow.
- Customizable Logic: Leverage JavaScript within function nodes to tailor data processing to your specific needs.
How To Use
- Create Example Data: Add a 'Function' node and configure the
functionCodeto generate your desired JSON data. The provided snippet uses a simple example:items[0].json = {"text": "asdf", "number": 1}; return items;. - Make Binary: Connect the output of the 'Create Example Data' node to a new 'Function' node. In this node, use the
functionCodeto convert your JSON data into a binary format. The example uses:items[0].binary = { data: { data: new Buffer(JSON.stringify(items[0].json, null, 2)).toString('base64') } }; return items;. - Write Binary File: Connect the output of the 'Make Binary' node to the 'Write Binary File' node. In the parameters, specify the
fileNamewhere the binary data will be saved (e.g.,test.json).
