A private alternative to online yaml to json tools

Convert YAML into JSON with pretty-printed output available by default. Use it for config migration, documentation examples, CI files, Kubernetes snippets, and data fixtures when another tool expects JSON. Blissum gives you a local YAML-to-JSON converter on macOS and iOS, so private configuration does not have to leave your device.

Blissum groups everyday code, text, data, and web utilities into one local app for Mac, iPhone, and iPad, which is especially useful where iOS has fewer native developer-tool options.
