Is my .env data sent to a server?

No. All parsing, editing, and conversion runs 100% in your browser. Your environment variables — which often contain API keys and secrets — never leave your device.

A .env file stores environment variables as KEY=VALUE pairs. It is loaded at application startup to configure the app without hardcoding values in source code. Libraries like dotenv (Node.js), python-dotenv, and godotenv parse these files automatically.

Should I commit .env files to git?

No. .env files typically contain secrets (API keys, database passwords, tokens) and should always be in .gitignore. Commit a .env.example file with placeholder values instead, so other developers know which variables are required.

What is the difference between .env, .env.local, and .env.production?

.env is the base file loaded in all environments. .env.local overrides it for local development and is never committed. .env.production overrides it for production builds. Most frameworks (Next.js, Vite, Create React App) follow this convention.

Can I convert .env to JSON or YAML?

Yes. This tool converts .env to JSON, YAML, and shell export format. This is useful for injecting environment variables into Docker containers, Kubernetes secrets, or CI/CD pipeline configurations.

About the .env Editor

Environment variables are the standard way to configure applications across environments without hardcoding values in source code. The .env file format is simple but easy to get wrong — duplicate keys, unquoted values with spaces, and accidental commits of secrets are common pitfalls. This editor parses, validates, and edits .env files with syntax highlighting, and converts between .env, JSON, YAML, and shell export format.

What this tool does

Parse & Validate

Parses .env syntax, flags duplicate keys, unquoted values with special characters, and invalid lines.

Visual Editor

Edit key-value pairs in a structured table view — no need to manually edit raw text. Add, remove, and reorder variables easily.

Format Conversion

Convert .env to JSON, YAML, or shell export format for use in Docker, Kubernetes secrets, or CI/CD pipelines.

Deduplication & Sort

Remove duplicate keys and sort alphabetically — useful for normalizing .env files before committing .env.example.

.env best practices

Always add .env to .gitignore — never commit secrets
Commit a .env.example with placeholder values for documentation
Use SCREAMING_SNAKE_CASE for variable names by convention
Quote values that contain spaces, #, or = characters
Use separate files per environment: .env.development, .env.production

Pipeline

JSON / YAML Converter — convert between .env and other config formats.
CI/CD Builder — reference your env vars in GitHub Actions or GitLab CI workflows.
