How do you generate images from a CSV file?

CSV-to-image generation is the classic bulk creative workflow: one template, hundreds of rows, hundreds of finished assets.

What a good CSV looks like:

Each column maps to a dynamic layer in your template (text or image).

Three ways to run it:

1. Google Sheets + no-code (easiest)

Upload or paste the CSV into Google Sheets, connect Make/Zapier/n8n → Layerre, and generate a variant per new/updated row.

2. Direct API loop (most control)

Parse the CSV in your script, then call Layerre once per row with layer overrides. Parallelize carefully and respect rate limits.

3. Canva Bulk Create (manual)

Canva's built-in Bulk Create can ingest a CSV inside the editor, but it is not an API: you still upload, generate, and download manually, with practical limits on volume.

Why teams outgrow CSV-in-Canva:

• No programmatic triggers (webhooks, CRM events, form submits)
• Manual download/ZIP handling
• Harder to re-run when data changes
• Limited integration into product backends

Best practices:

• Normalize image URLs (HTTPS, publicly fetchable, consistent aspect ratios)
• Keep text columns short enough for the template layout
• Include an id column so you can name and track output files
• Validate 5 sample rows before running the full batch
• Prefer Sheets/Airtable over static CSV when data updates often

Airtable bases, Notion databases, and Shopify product exports can replace CSV as the data source while keeping the same template mapping.
