n8n Workflow: Product Image Creative Brief Matrix from JSON to CSV

Turn your product catalog + approved scenes into a validated CSV creative brief matrix

This n8n workflow takes your small product catalog JSON, approved scene descriptions, and target aspect ratios—and outputs a downloadable, review-ready CSV matrix of product-image creative briefs with unique IDs and validation checks.

What this workflow does

Run it manually in n8n to generate a structured set of creative briefs for handoff to your creative team or QA review:

• Loads your inputs: brandStyle, aspectRatios, product catalog JSON (SKU, subject, must-keep details, optional referenceAsset), and approved scenes JSON (each with a name and setting).
• Validates the inputs: checks required fields, ensures unique SKUs, verifies supported aspect ratios, and enforces a maximum of 100 brief combinations.
• Builds the brief matrix: creates a creative brief for every product × scene × aspect ratio combination, including a standardized prompt, a review checklist, a status field, and a unique brief ID.
• Exports to CSV: converts the matrix into a CSV file with spreadsheet-formula injection protection, then provides it as a downloadable file from the final binary output.

Use cases

• Generate consistent product-image prompts for e-commerce creatives from a JSON catalog and approved scene settings.
• Produce QA-friendly brief sheets for each SKU across multiple aspect ratios (e.g., for listing pages and ads).
• Standardize review and handoff by attaching a checklist and status per brief in the exported CSV.

Technical details

• Trigger: Manual Trigger
• Workflow logic nodes: set, code, sticky note
• No external credentials: the workflow runs locally using the provided JSON inputs and outputs the CSV for download.

Ideal for n8n users and automation engineers who want a reliable, validated creative brief matrix workflow—from JSON to CSV—without extra setup.
