Input

Output

YAML, JSON, and TOML are structurally equivalent but syntactically incompatible — YAML uses indentation and colons, JSON uses braces and quotes, TOML uses sections and equals signs — so CI migrations or Kubernetes-to-Helm rewrites that mix formats need a converter that handles multiline strings and nested arrays, which this tool does locally in the tab.
