Env File Doctor
Lint .env files for duplicates, malformed lines, inline comments and likely secret leaks.
Paste a .env file to scan it.
About this tool
Paste a .env file and get a full report: duplicate keys, missing '=', invalid identifiers, unquoted values with spaces, inline comments, CRLF warnings, suspicious empty values and high-entropy strings that look like uncommented secrets. A fixed output panel applies conservative auto-fixes (dedupe last-wins, quote values with spaces, normalize line endings).
