JSONMASTER.com

Like most developers, I’ve used JSON for years without thinking much about it.

JSON.stringify()
JSON.parse()
Done. Ship it.

But while working on a tool that processes large and messy JSON payloads, I hit a wall:

• Browsers freezing on big files

• Weird performance drops

• Precision bugs with large numbers

• Security concerns around untrusted input

So I decided to actually understand what happens behind the scenes. And created jsonmaster.com
