What formats does this converter support?

The converter handles YAML, JSON and TOML in any direction — YAML to JSON, JSON to TOML, TOML to YAML, etc. It supports pretty printing with configurable indentation and optional key sorting.

Why would I need to convert between YAML and JSON?

Many DevOps tools use different configuration formats. Kubernetes uses YAML, npm uses JSON, Rust tools use TOML. Converting between them is a common task when migrating configurations or copying snippets from documentation.

Note on TOML: TOML supports some data types that don't map cleanly to JSON/YAML (e.g. datetime, integers vs floats). Complex nested TOML with array-of-tables may require manual review after conversion.
