使用方法
- Paste or type your .env file contents into the text area。
- Errors and warnings appear instantly: duplicate keys, keys starting with a digit, unmatched quotes, and lines with leading whitespace are flagged。
- Each issue shows the line number, severity badge, message, and the raw offending line。
- Fix issues in the editor and watch the error/warning counts drop to zero。
範例
- Having DATABASE_URL appear on two lines triggers an error "duplicate key" on the second occurrence。
- A line like "1FOO=value" triggers an error because .env key names must start with a letter or underscore。
