About YAML to .env Conversion
Modern applications often store configuration in YAML files for human readability, but deployment environments (Docker, Kubernetes, cloud platforms) expect environment variables. This converter bridges that gap by flattening nested YAML structures into UPPER_SNAKE_CASE environment variable names. For example, database.host: localhost becomesDATABASE_HOST=localhost. Arrays are joined as comma-separated values. The conversion happens entirely in your browser — no data is sent to a server.
Private & free — this tool runs entirely in your browser.
