}About .env File Parser
The .env File Parser reads dotenv-format content (KEY=VALUE pairs) and parses it into a structured table showing each variable's key and value. It handles single-quoted and double-quoted values by stripping the surrounding quotes, strips inline comments starting with " #", preserves comment lines in the display for context, and skips blank lines and malformed entries. The parsed result updates in real time as you type.
After parsing, the tool lets you export the variables in three formats: JSON (standard JavaScript object format), YAML (key: "value" pairs suitable for Kubernetes, Helm, or CI/CD configuration), and TOML (key = value pairs with proper type detection for booleans and numbers). This makes it easy to migrate .env configuration to other configuration systems or to validate that your .env file is syntactically correct.
This tool is used by backend developers inspecting application configuration, DevOps engineers converting .env files to Kubernetes secrets or ConfigMaps, CI/CD pipeline maintainers validating environment variable definitions, and developers onboarding new team members who need to understand the project's configuration structure. All parsing and conversion happens entirely in the browser — sensitive API keys and credentials never leave your device.
Key Features
- Parses KEY=VALUE dotenv format with support for single and double quoted values
- Strips inline comments (text following " #") from values automatically
- Displays comment lines in the table for context, visually distinguished from key-value rows
- Shows variable count and comment count summary below the table
- Export to JSON (object format), YAML (key: "value"), or TOML (key = value with type inference)
- One-click copy of the exported output to clipboard
- 100% client-side processing — API keys and secrets never leave your browser
- Real-time parsing — table and export output update instantly as you edit the .env content
Frequently Asked Questions
What .env syntax does this parser support?
The parser supports the standard dotenv format: KEY=VALUE pairs, one per line. Values can be unquoted, single-quoted ('value'), or double-quoted ("value") — surrounding quotes are stripped. Inline comments (text following " #" with a space before the hash) are stripped from values. Lines starting with # are treated as comments and displayed in the table but not included in the export.
How does the parser handle quoted values?
If a value starts and ends with the same quote character (either single or double), the surrounding quotes are removed. For example, DB_PASSWORD="s3cret" becomes DB_PASSWORD: s3cret in the parsed output. This mirrors the behavior of most dotenv libraries like dotenv (Node.js) and python-dotenv.
What are inline comments and how are they handled?
An inline comment is text that appears after a space-hash (" #") in a value. For example, PORT=3000 # default port — the parser strips " # default port" and keeps only "3000". This matches the behavior of most dotenv parsers that support inline comments.
What is the difference between the JSON, YAML, and TOML export formats?
JSON exports all variables as a JavaScript object: {"KEY": "value"}. YAML exports as key: "value" pairs, one per line, suitable for Kubernetes ConfigMaps or GitHub Actions. TOML exports as key = value with type inference: boolean values (true/false) and numbers are unquoted, strings are double-quoted. Choose based on where you intend to use the configuration.
Can I use this to validate my .env file?
Yes. Pasting your .env content shows you exactly which lines were parsed as variables and which were skipped (due to missing = sign or blank lines). The variable count shows how many valid KEY=VALUE pairs were found. If a variable you expected is missing from the table, check that line for syntax issues.
How do I convert a .env file to a Kubernetes Secret or ConfigMap?
Parse your .env file and switch to the YAML export format. The output can be used as the data section of a Kubernetes ConfigMap. For Secrets, you would additionally need to base64-encode each value. Alternatively, use kubectl create secret generic my-secret --from-env-file=.env directly in the terminal.
Is it safe to paste API keys and passwords into this tool?
Yes. All parsing is done entirely within your web browser using JavaScript. No content is sent to any server, logged, or stored in any database. It is safe to paste .env files containing API keys, database passwords, and other credentials.
Does this tool handle multi-line values?
The current parser is line-based and does not support multi-line values (values spanning multiple lines with backslash continuation or quoted newlines). For multi-line values, the first line is parsed and subsequent continuation lines are skipped or treated as separate entries. If you need multi-line support, consider using a dedicated dotenv library in your runtime environment.
