Neko Nik

Neko Nik is a straightforward, no-frills web tool for working with JSON data. You paste your JSON into the browser, and it instantly displays it in a collapsible tree view. This makes it easy to navigate complex nested objects and arrays. The tool also provides basic but essential formatting functions: you can beautify minified JSON for readability or minify formatted JSON to save space. There's also a share feature that creates a link to your formatted data.

It works entirely in your browser, with no need to create an account or install software. The interface is simple, with a clear text editor pane and a visual tree panel. You can switch between a dark and light theme. While it doesn't have advanced features like validation, schema generation, or direct editing within the tree, it covers the core tasks of viewing and cleaning up JSON quickly and reliably.

This tool is most useful for developers and anyone who regularly works with APIs or configuration files. If you need to check the structure of an API response, make a messy JSON file human-readable, or quickly share a snippet of formatted data with a colleague, Neko Nik gets the job done without any setup.
