Why Tools Ku
- 100% free, no signup
- Data stays in your browser
- Indent, minify, fold, syntax highlight
- For API debugging, configs, and logs
JSON powers APIs, configs, and logs. Unformatted JSON is hard to read; invalid JSON breaks parsers. Tools Ku formats, minifies, validates, and converts XML—all client-side, so secrets never hit a server.
Built for daily dev work: inspect API responses, tidy config files, and compare versions with folding and custom indent.
Steps
- Paste or type JSON in the editor
- Click format to beautify or minify to strip whitespace
- Invalid JSON shows parse errors—fix brackets, quotes, commas
- Copy, download, or convert to/from XML as needed
FAQ
- Is my JSON sent to a server?
- No. All processing is local in your browser.
- How large a JSON file is supported?
- Limited by browser memory; a few MB usually works. Split or use CLI tools for very large payloads.
- How do I find syntax errors?
- The editor validates as you work; invalid JSON won't format and shows a parse failure—check brackets and commas.
- Can I minify JSON?
- Yes—minify removes newlines and extra spaces for smaller payloads.
- JSON ↔ XML support?
- Yes—built-in conversion for legacy systems and XML configs.
- Signup required?
- No—unlimited use without an account.
