jsontoimg

Testimonial Images from CRM or Review Data

A testimonial image generator turns one approved quote into a branded card. jsontoimg fills the quote, customer name, role, and avatar on named layers, so a spreadsheet of reviews becomes a folder of consistent social images. It suits marketing teams with a steady stream of customer quotes and no designer free to lay out each one.

Layers that change per card

  • quote: the text, with auto-fit turned on so long quotes shrink rather than overflow
  • name and role: short strings
  • avatar: an image layer that takes a public https file ending .png, .jpg, .jpeg, or .webp
  • company_logo: optional image layer

Keep the quote marks, rules, and brand colours in the design. Changing them then means one template edit, not a card-by-card fix.

Render a card

{
  "template": "<design-id>",
  "format": "png",
  "layers": {
    "quote": { "text": "We replaced a weekly design chore with a script." },
    "name": { "text": "Priya Raman" },
    "role": { "text": "Head of Growth, Northwind" },
    "avatar": { "image_url": "https://example.com/avatars/priya.jpg" }
  }
}

Test the extremes

Render a one-line quote, a four-line quote, and a long name before you run the list. Auto-fit handles overflow, but a layout tuned for a short quote can look cramped at the longest. Use "dryRun": true to validate a payload without spending a credit.

Get permission first

A rendered card is a published claim. Only use quotes the customer has agreed to share, and store the approval next to the row. jsontoimg does not check consent or verify that a quote is genuine; that belongs in your review step before the data reaches the template.

Where the data lives

A CRM export, a review spreadsheet, or an Airtable base all work. For a sheet, the Google Sheets add-on renders selected rows. For Airtable, use the custom extension. For anything event-driven, use n8n.

How do I stop long quotes overflowing the card?

Turn on auto-fit for the quote layer and render a very short and a very long quote before the full run.
