🚀 I Built a Free JSON Formatter & Developer Tools Platform
As a backend engineer, I constantly switch between tools for formatting, validating, and converting JSON, XML, YAML, and CSV data.
Most online tools are:
Cluttered with ads
Slow
Limited in functionality
Or require login
So I decided to build my own.
What It Does
It currently includes:
JSON Formatter
JSON Validator
JSON Viewer
JSON Minifier
JSON to XML
JSON to CSV
JSON to YAML
CSV to JSON
XML Formatter
XML Validator
YAML Formatter
Base64 Encode / Decode
URL Encode / Decode
JWT Decoder
JSON Diff
JSON Schema Generator
All tools run directly in the browser.
No data is stored.
Why I Built It
I wanted:
⚡ Fast load
🧠 Clean UI
🔒 Client-side processing
📱 Mobile friendly
🌙 Dark theme
🧩 Developer-focused layout
It’s still early, but I’m actively improving it.
If you want to try it:
Feedback welcome.

This is exactly the kind of tool devs actually need. I deal with JSON daily, and most formatter sites are full of ads or freeze on large files. The fact that everything runs in the browser with no login is a huge plus. One small suggestion from my experience — add a “copy formatted JSON” button and auto-detect errors line number, it saves a lot of time when debugging.
