Kson is a superset of JSON

KSON combines the strengths of YAML and JSON

With KSON you can write files that are easy to read, edit, and debug—without worrying about invisible whitespace errors or missing commas.

YAML promises human-friendly config, but in practice we struggle with whitespace sensitivity, poor error feedback, and opaque advanced features.
JSON solves some of these problems but introduces its own: excessive quotes, no comments, strict comma rules, and nested structures that complicate diffs.

KSON offers the best of both worlds: the readability of YAML with the robustness of JSON—and more.
