AI rewrite single field, keep other fields?

Help me Build my Workflow
1

Hi everyone,

I’m using n8n to process a CSV file (which I first download and decompress). The CSV contains product data (fields like product_name, description, category, etc.).
I can already see each product as a table/JSON and mapping to WooCommerce works fine.

My goal:
I want to use the OpenAI node (“Message a model”—is this the right approach?) to rewrite only a specific field like product_name using AI. Ideally, the new result should either replace the original field or be added as a new field (e.g., product_name_new_ki).
All other fields in the item should remain unchanged.

The problem:
The AI node always returns only the new text field; all other fields/structure are lost.

Question:
How do you use n8n to change or add just one field with AI, without losing the rest of the item’s data? Is there a simpler or better way than using the Merge node? What’s your best practice for processing several fields with AI in one item, without losing the other data?

Thanks for any tips or example workflows!

Hey @waddaplaya4k hope all is well. Welcome to the community.
It is difficult to understand the issue without some type of visuals, could you please share your workflow and maybe some screenshots explaining your problem? Try to minify the explanation to only what doesn’t work, a complete reproducible example would be the best.

For example: I do X, I expect Y, but I get Z (see the image).
