Frequently asked questions
Which TOML version is supported?
TOML 1.0, including tables, arrays of tables, inline tables, dates and multi-line strings.
How are nested JSON objects written to .env?
Keys are joined with underscores and uppercased, so { "db": { "host": "x" } } becomes DB_HOST=x.
Are values in .env files typed?
No. Environment variables are always strings, so values stay as text when converting from .env.
