About Env Parser Online
This tool parses .env files (the dotenv format used by Node.js, Python, Ruby and many other tools to load environment variables). It validates syntax, detects duplicate keys, identifies missing or unset variables, and converts between .env and JSON/YAML formats.
The .env format is simple in principle but full of subtle pitfalls: unquoted values with spaces, escape sequences in strings, comments in the wrong place, BOM characters from Windows editors. The parser handles all of these correctly and reports any issues.
Use it before deploying to validate that your .env.production matches your .env.example schema, when migrating between environments, or when converting environment variables into a format another tool can consume.
How to use this tool
How to parse a .env file into key-value pairs
Paste your .env content
Drop the lines from your `.env` (or any KEY=value list) into the ".env" field. The parser splits on `\n`/`\r\n` and processes line by line.
What's skipped and trimmed
Blank lines and lines starting with `#` are skipped as comments. Lines without `=` are dropped silently. Each key and value is trimmed; surrounding `"` or `'` quote pairs on the value are stripped.
Press Run
Result returns entries (array of `{key, value}` objects in source order) and count (the number of parsed entries). Duplicates are preserved — the parser doesn't dedupe keys.
Limits vs full dotenv
There's no variable interpolation (`${OTHER}`), no multi-line values, no export prefix handling, no escape sequences. For full parity with dotenv-style runtimes, run your tool's loader instead — this is a quick sanity-check.
