More About Paint By JSON

Paint By JSON

Paint By JSON transforms your Figma workflow by connecting designs directly to live API data. Replace placeholder text with real names, prices, dates, and content from any JSON endpoint—ensuring your prototypes reflect actual product conditions before development begins.

Product Highlights

  • Real API Connection: Connect any REST API endpoint with custom headers and authentication, previewing JSON responses directly within the plugin.
  • Smart Data Mapping: Bind JSON paths to Figma layer names with portable mappings that survive file refactors and team library updates.
  • Transform Pipeline: Apply text truncation, currency formatting, date parsing, and conditional logic to shape raw data before it reaches your canvas.
  • Reusable Palettes: Save complete data configurations—including endpoints, headers, and mappings—as reusable palettes for instant application across any frame.
  • Privacy-First Architecture: All API calls execute in your local plugin iframe; responses and credentials never leave your machine or touch external databases.

Use Cases

  • Realistic Prototyping: Test designs against actual user names, product titles, and content lengths to catch truncation and layout breaks early.
  • Design Systems Documentation: Populate component libraries with authentic data samples that demonstrate how designs perform with real-world edge cases.
  • Engineering Handoff: Export populated frames as JSON, Markdown, or Spec Frames containing both visual design and the data structure behind it.
  • Dynamic Content Testing: Iterate array responses across repeated component instances to validate grid layouts and list behaviors.

Target Audience

Paint By JSON serves product designers, design systems teams, and UX professionals who need to validate interface designs against production data before handoff. It's ideal for teams shipping data-rich applications where placeholder content fails to reveal true design constraints.
