Frequently Asked Questions

Does it handle quoted values?
Yes. Single-quoted values are taken literally. Double-quoted values support escape sequences like \n and \". Unquoted values strip inline comments.
What validation does it perform?
It checks for invalid key names (must start with letter/underscore, alphanumeric only) and flags duplicate keys with line references.
What is the .env.example output?
It generates a template with all keys but empty values, preserving any inline comments as documentation for other developers.
Is my data sent to a server?
No. All parsing runs entirely in your browser. Nothing is uploaded or stored.
