Env to JSON
Convert environment variable (.env) files into valid JSON objects instantly. This free online tool transforms dotenv-style KEY=value pairs into pretty-printed JSON, perfect for configuration management, data migration, and integrating legacy environment files with modern JSON-based systems.
The converter processes standard dotenv syntax with precision: each line is parsed as a KEY=value pair where blank lines and comments (lines starting with #) are automatically ignored. Quoted values have their surrounding quotes stripped automatically—single or double quotes both work seamlessly. If a key appears multiple times, the last occurrence wins, matching the behavior of most environment variable loaders. The output can be formatted with adjustable indentation from 0 spaces (compact representation) to 8 spaces (highly readable), giving you full control over the JSON output format.
Security and privacy are built in. Everything runs entirely in your browser with zero server-side processing, so sensitive configuration data, API keys, and secrets never leave your device. The live tally shows exactly how many keys were parsed and the exact size of the resulting JSON output. Once converted, copy the JSON directly, download it as a .json file, or pipe it to other tools for additional processing. Perfect for DevOps workflows, deployment automation, and configuration management tasks.
FAQ
What is the dotenv format?
Dotenv is a simple text format for storing environment variables, with one KEY=value pair per line. Comments start with # and empty lines are ignored. Commonly used in .env files for application configuration, especially in Node.js, Python, and Ruby projects.
What happens when a key appears multiple times?
The last occurrence of each key takes precedence, replacing any earlier values. This behavior matches standard environment variable loaders, ensuring predictable results when processing configuration files with duplicate keys.
How are quoted values handled?
If a value is surrounded by matching single or double quotes, the quotes are automatically removed, leaving just the content. Unquoted values and values with mismatched quotes are preserved exactly as they appear in the input.
Can I customize the JSON indentation?
Yes. The indent option lets you choose from 0 (compact, minimal size) to 8 spaces (highly readable). Select 0 for minimal file size or a higher value for easier manual inspection and editing of the JSON.
Is my configuration data uploaded anywhere?
No. All conversion happens entirely in your browser using client-side processing. Your data never touches any server, making it completely safe for sensitive configuration files, API keys, and production secrets.
