.env
A .env file is a convention, not an IETF standard. Implementations disagree on expansion, multiline values, and export prefixes.
Common uses
- Local development secrets
- Process environment bootstrapping
Strengths
- Simple
- Widely understood in web apps
Weaknesses
- Easy to commit by accident
- Dialect differences
- No types
Compatibility. ConvertPass accepts export prefixes and quoted values. It does not expand $VARS.
Size and quality. Tiny. Not an interchange format for large datasets.
How to open it. A text editor. Never a public pastebin.
How to convert it. .env to JSON and JSON to .env for flat objects.
Security and privacy. These files often contain tokens. ConvertPass processes them locally. Reset the tool. Add .env to .gitignore.
