Prepare CV Data for Translation

Why we split into separate items:

The translation API accepts one word at a time. To translate all CV fields, we need to call the API once per field. By splitting the array into separate items, n8n can process each one through the subsequent nodes.

The Split Out node:

The Split Out node takes an array field and creates a separate n8n item for each element:

• Input: 1 item with fieldsToTranslate containing 6 objects
• Output: 6 separate items, one for each object in the array

This is one of the most useful nodes for preparing data for batch processing. Whenever you have an array that needs to be processed item by item, Split Out is your go-to node.

What happens next:

Now that each field is a separate item, in the next challenge you'll send each one to the translation API. n8n automatically processes all 6 items through the subsequent nodes, calling the API for each Wookiee growl.

Why the API provides fieldsToTranslate:

In real-world scenarios, APIs often provide data in formats optimized for processing. The fieldsToTranslate array is pre-built to make translation easy - each object has a field name and value to translate, ready for the translation API.
