Streamline Your DevOps Workflow
Moving from local development to production often involves migrating your .env configurations to a hosting provider. Manually typing dozens of variables into a web dashboard is tedious and prone to errors.
Our .env to Config Converter automates this process by transforming your standard dotenv format into platform-specific configuration blocks.
How to use the .env Converter
- Paste your .env content: Copy the contents of your local
.envfile into the input editor. - Select your target platform: Choose between Vercel (JSON) or Netlify (TOML).
- Copy the configuration: Grab the generated code and paste it into your
vercel.jsonornetlify.tomlfile.
Supported Formats
- Vercel: Generates the
"env"object forvercel.json, compatible with all Vercel deployment versions. - Netlify: Generates the
[build.environment]section fornetlify.toml, allowing you to set build-time and runtime variables.
⚠️ Security Warning:
Always ensure your .env file and any derived configuration files containing secrets are included in your .gitignore. For high-security secrets, use the platform's built-in encrypted environment variable management tools instead of configuration files.
Frequently Asked Questions
Why should I use a config file for environment variables?
Using vercel.json or netlify.toml allows you to version control your non-sensitive environment configuration (like public API endpoints or build flags) alongside your code. It also makes project initialization faster for team members.
Is it safe to put secrets in vercel.json or netlify.toml?
No. You should never put sensitive secrets (like private API keys or database passwords) in configuration files that are committed to git. Use the platform's dashboard or CLI to add sensitive secrets directly to their secure vault.
Does this tool handle multi-line environment variables?
Currently, this tool supports single-line KEY=VALUE pairs. For complex multi-line variables (like private keys), it's recommended to use the platform's native secret management UI.
What is the difference between Vercel and Netlify env formats?
Vercel typically uses a 'env' key in vercel.json which is a flat JSON object. Netlify uses a [build.environment] section in netlify.toml which follows the TOML specification.
