Description
DuskTools | JSON Formatter helps you format, minify, and validate JSON in one click, without sending data to a server.
What you get:
• Format - pretty-print JSON with readable indentation
• Minify - compress JSON to a single line
• Validate - catch JSON syntax errors before you ship
• Paste and copy - pull JSON from the clipboard and copy results back
How it works:
Paste or type JSON in the popup, choose format or minify, and copy the result when you are ready. Everything runs locally in Chrome: no background script, no remote API, and no analytics in this extension.
