כיצד זה עובד

A malformed .env file causes confusing config bugs — a duplicate key, a stray space around "=", an unquoted value with a space. This lints your file and cleans it up, all locally (important, since .env files hold secrets).

1
You paste your .env
Each line is parsed: comments and blanks are skipped, "export" prefixes handled.
2
It checks for problems
Duplicate keys, spaces around "=", invalid key names, non-uppercase keys, empty values, and unquoted values containing spaces or "#" are flagged with line numbers.
3
It produces a cleaned file
Keys are de-duplicated (last value wins), sorted alphabetically, and values are quoted where needed.
4
And a .env.example
The same keys with blank values — ready to commit so teammates know which variables to set, without leaking secrets.

.env files are full of secrets — API keys, database passwords. This tool parses everything in your browser and never uploads a thing, so it's safe to paste a real file.
