I often need quick JSON utilities while debugging APIs, cleaning payloads, or converting data for spreadsheets, so I put together a simple browser-based toolkit:

https://jsonutilitykit.com/

It currently includes:

• JSON Formatter
• JSON Validator
• JSON Viewer
• JSON Minifier
• JSON Editor
• JSON to CSV Converter
• CSV to JSON Converter

The tools are designed for quick use without creating an account. They are especially useful when you want to format, inspect, or validate JSON snippets during development.

I am still improving the examples, edge cases, and documentation. Feedback from developers who work with JSON regularly would be useful.
