This n8n workflow automates the process of reading a binary file, converting its contents to JSON, and extracting specific key-value pairs based on user input. It begins with a manual trigger, allowing the user to initiate the process on demand. The workflow then constructs the file path dynamically using a simple function node, leading to a read binary file node that retrieves the binary data from the specified location. The binary data is subsequently transformed into JSON format, enabling easy data manipulation. The final step involves extracting a specific value associated with a key, or falling back to a default value if the key is not present. This functionality is useful in scenarios where binary data files store configuration or data in JSON format, and specific entries need to be retrieved automatically. Overall, the workflow streamlines data extraction and enhances automation for managing binary files containing structured information.
