.env to JSON & ConfigMap Converter (Docker & K8s)

Convert .env environment files into JSON objects, Docker Compose YAML, or Kubernetes ConfigMap manifests with secret masking, type coercion, and variable expansion support.

Samples:
.env Environment File Input25 lines
Converted Output (JSON)
Variables Count16
Sensitive Keys5
Output Size632 B
Security GuardProtected

100% Client-Side Privacy

Your production passwords, AWS credentials, and API secrets are processed locally in your browser memory and never transmitted anywhere.

DevOps Manifest Export

Transpile raw environment variables straight into Docker Compose YAML or native Kubernetes ConfigMap resource manifests.

Intelligent Dotenv Parsing

Full support for variable substitution (${VAR}), smart type coercion (numbers & booleans), quote stripping, and sensitive key masking.

Technical Reference & Architecture Guide

.env to JSON & ConfigMap Developer Guide — Reference Guide

Comprehensive reference for parsing .env files into JSON objects, Docker Compose environment blocks, and Kubernetes ConfigMap manifests with secret masking.

Key Parameters & Controls

maskSecretsboolean

Obfuscate sensitive values containing passwords, keys, secrets, or tokens.

typeCoercionboolean

Cast numeric strings to numbers and true/false to boolean values instead of keeping strings.

outputFormatstring ('json' | 'docker' | 'k8s')

Target configuration manifest structure to generate from environment keys.

expandVariablesboolean

Interpolate ${VAR} environment references using previously declared keys.

Pro Tips & Best Practices

Always quote string values containing spaces, hash symbols (#), or multi-line certificates in .env files.

In Kubernetes, split public application variables into ConfigMaps and sensitive credentials into Secret manifests.

Use Docker Compose environment map syntax (KEY: value) for easy overrides via host environment.

Common Gotchas & Troubleshooting

Wrap the value in double quotes (") to inform the dotenv parser that the hash sign is literal data rather than a comment.

Ensure escaped newlines (\n) are preserved or wrap the entire PEM block inside quotes.

Frequently Asked Questions

Are my database passwords or API keys sent to any external server?▼

No. The parsing and transformation logic run 100% locally in your web browser.

Can I convert JSON back into .env format?▼

Yes. The tool supports bidirectional syntax conversion between .env and JSON.

Does this tool support variable expansion like ${DB_HOST}?▼

Yes. Variable substitution is resolved sequentially from top to bottom.

What Kubernetes resource structure is generated?▼

It outputs a standard apiVersion: v1, kind: ConfigMap manifest with a metadata block and data map.
