JSON List Visualizer

2026-01-06

I built a quick tool for visualizing JSON lists as cards. It's designed for API responses that return arrays of objects — like the OpenAI models endpoint or any paginated API.

How it works

Paste your JSON into the textarea and hit Visualize (or press Ctrl+Enter). The tool will:

  1. Parse the JSON
  2. Find the array — either at the root level, or inside a data property
  3. Render each object as a card with all its key-value pairs

Why?

Mostly just readability. I find it easier to look through these cards than to scroll through raw JSON.
