How to Use .env File Validator
Paste the contents of your .env file into the editor. The tool validates every line instantly, flagging syntax errors like missing equals signs, unclosed quotes, or whitespace around keys. It also checks the entire file to warn you if you have duplicated environment variables that might cause override bugs in production. Click "Sort Keys A-Z" to organize your variables cleanly while preserving your comments.
