If you work with APIs daily, you already know this:
Most JSON viewers are… basic.
They pretty-print JSON.
They collapse/expand nodes.
And that’s about it.
But modern API responses aren’t simple anymore — they’re large, nested, and full of data that needs interpretation, not just formatting.
So I built JSON Vision Pro.
🚨 The Problem
While working with APIs, I kept running into the same issues:
- Large JSON arrays were hard to read
- JWT tokens required external tools to decode
- Image URLs had to be opened manually
- Comparing API responses was painful
Every time, the workflow looked like this:
- Open JSON
- Copy something
- Go to another tool
- Come back
- Repeat
It breaks focus. It wastes time.
💡 The Idea
What if a JSON viewer could understand the data, not just display it?
Instead of treating everything as text:
- Arrays become tables
- Tokens become readable
- URLs become previews
That’s the core idea behind JSON Vision Pro.
🚀 What JSON Vision Pro Does
📊 Table View for Arrays
JSON arrays are automatically convertible into clean table views.
No more scanning through nested objects — just read it like structured data.
🔑 Built-in JWT Decoder
Paste or detect a JWT → instantly see:
- Header
- Payload
- Expiration
No more jumping to external websites.
🎨 Smart Visual Previews
The extension automatically detects and renders:
- 🖼️ Image URLs → inline thumbnails
- 🎨 Color codes → color chips
- ⏱️ Unix timestamps → readable dates
This alone removes a lot of manual effort.
⚖️ Response Comparison
Compare two API responses side-by-side:
- See what changed
- Highlight differences instantly
Super useful for debugging and QA.
🔍 Search & JSONPath
- Search across entire JSON
- Use JSONPath queries like:
$.users[*].name
Works well even with large payloads.
🕒 Time Machine (History)
Quickly switch between recent API responses and compare them.
🧠 Why This Matters
Most tools treat JSON as text.
But developers don’t think in raw JSON — they think in:
- Data structures
- Patterns
- Differences
The goal was simple:
Reduce friction between “seeing data” and “understanding data”
⚡ How to Use
- Install the extension
- Open any API endpoint returning JSON
- The viewer activates automatically
Works with:
- REST APIs
- Local JSON files
- Any
application/jsonresponse
🔒 Privacy First
- 100% local processing
- No tracking
- No data leaves your browser
💭 Final Thoughts
This started as a small frustration.
But once you start working with:
- Table views instead of raw arrays
- Inline previews instead of guessing
- Built-in tools instead of switching tabs
…it’s hard to go back.
🚀 Try It Out
If you work with APIs regularly, I’d love your feedback.
JSON Vision Pro is available for Edge and Firefox.
📢 Feedback
If you try it:
- Let me know what’s missing
- Suggest features
- Or just tell me how your workflow feels now
That’s how this gets better.
