ENV / Shell / Docker Converter
Convert .env files to JSON, YAML, TOML, shell export, and Docker ENV instantly in your browser. Nothing is uploaded — all conversion is client-side.
What Is an ENV Converter?
The ENV Converter transforms environment variable files between six formats: .env (dotenv), JSON, YAML, TOML, shell export, and Docker ENV. Developers juggle these formats constantly — a .env file for local development, shell exports for CI scripts, Docker ENV directives for container builds, and JSON or YAML for infrastructure-as-code tools like Terraform and Ansible. Manually rewriting variables across formats is tedious and error-prone: a missing quote or wrong escape character can break a deployment. This converter handles multiline values, strips comments, and preserves key-value integrity across every target format. The entire conversion runs client-side in your browser, so secrets like API keys and database credentials are never transmitted over the network.
How to Use the ENV Converter
Select your source format from the "From" dropdown — .env, JSON, YAML, TOML, shell export, or Docker ENV. Paste your input into the left panel. Choose the target format in the "To" dropdown and the converted output appears instantly on the right. Use the swap button to reverse the conversion direction. Copy the result with one click or adjust the input and re-convert. The converter supports multiline quoted values, strips comments automatically, and flags malformed input with a clear error message pointing to the problem.
Why Consistent Environment Variables Matter
Environment variables control database URLs, API keys, feature flags, and service endpoints across every stage of your pipeline. A mismatch between your local .env and the shell exports in your CI script can cause silent failures that only surface in production. Docker Compose, Kubernetes ConfigMaps, and serverless platforms each expect a different format for the same data. Standardizing how you convert between these formats eliminates an entire class of deployment bugs. By keeping the conversion local and offline-capable, you avoid exposing secrets to third-party services — critical for SOC 2 and ISO 27001 compliance.
Frequently Asked Questions
Is my data safe?
Yes. All conversion happens entirely in your browser using JavaScript. Nothing is sent to any server. You can even use this tool offline.
Does it support multiline values?
Yes, quoted multiline values in .env files are supported. For example: CERT="line1\nline2".
What happens with comments?
Comments (lines starting with #) are stripped during conversion. They are not preserved in the output format.
