Find duplicate keys, unquoted values with spaces, missing values, invalid key names, and unclosed quotes. View variables in a sortable table grouped by prefix. Auto-detect and mask sensitive values like passwords, API keys, and tokens. Generate .env.example files with values stripped. Compare two .env files to see added, removed, and changed variables. Convert between .env, JSON, YAML, and TOML formats. All processing runs in your browser - your secrets never leave your device.
