Workflow to read binary files, convert them to JSON, add metadata (key-value pairs) in both English and Chinese, and write them back as binary files.

About This Workflow

This workflow is designed to process binary files, transforming them into structured data that can be enriched with metadata. It specifically supports the generation of metadata in both English (en) and Chinese (zh) before writing the modified binary data back to storage. The process involves reading binary data, converting it to JSON, applying key-value pair modifications, and then converting it back to binary for output. A loop mechanism ensures all items are processed.

Key Features

Reads binary files.
Converts binary data to JSON for easier manipulation.
Allows setting custom key-value pairs for metadata.
Supports generating metadata in multiple languages (English and Chinese).
Converts JSON data back to binary.
Writes processed binary files to storage.
Includes a batch processing and looping mechanism to handle multiple items.

How To Use

On clicking 'execute': This node acts as the manual trigger for the workflow.
SplitInBatches: This node is used to process items one by one (batchSize: 1). It takes the input from the trigger.
Config: This Function node is crucial for defining the file path, key, and value for the metadata to be added. It uses item.file, item.key, and item.value from the input. The file path is constructed relative to the n8n local files directory.
Read Binary Files: Reads the binary file specified by the file property from the Config node.
BinaryToJSON: Converts the binary content read by the previous node into a JSON object. The options parameter can be used for specific conversion settings.
SetKeyValue: This Function node dynamically adds or updates a key-value pair in the JSON object. It uses the key and value defined in the Config node. This is where you would set your English and Chinese metadata.
JSONToBinary: Converts the modified JSON object back into binary data. The mode: 'jsonToBinary' is essential here.
Write Binary File: Writes the binary data generated by JSONToBinary to a file. The fileName is taken from the Config node's file property.
Repeat: This If node checks if there are more items to process. If noItemsLeft is true, it proceeds to Done. Otherwise, it loops back to SplitInBatches.
Done: This Function node logs 'Done!' to the console, indicating the workflow has completed.
