About

JSON to YAML re-writes JSON documents as human-friendly YAML on your computer. Key order is preserved, non-ASCII characters stay readable instead of becoming escapes, and the output uses safe dumping only.

Free converts 5 files a day in block style. Pro removes the limit and adds compact flow style. One key covers up to 3 Windows PCs.

What it does

  • Key order preserved exactly
  • Unicode stays readable (no escapes)
  • Safe dumping only — nothing executed
  • Compact flow style in Pro
  • Free: 5 files a day, up to 30 MB
  • 100% local: files never leave your computer

FAQ

Is anything uploaded?

No. The app works fully offline; only license activation and update checks touch the network.

Why YAML?

Configs and CI pipelines read better as YAML — same data, friendlier syntax.

What do I get after payment?

A license key that unlocks Pro on up to 3 Windows machines for 12 months.
