Is the env to json converter free?

Yes, completely free. No sign-up, no daily limit, no watermark on the output.

Are data types preserved?

Yes. Numbers and booleans are auto-detected and written as proper JSON types instead of staying as strings.

How are comments handled?

Lines starting with # are ignored, just like the dotenv loaders in Node.js, Python, and Docker handle them.

Are quoted values supported?

Yes. Single and double-quoted values are correctly unwrapped, so the JSON ends up with the actual string inside.

Does this support nested JSON?

ENV files are flat by design, so the output JSON is also a flat object. If you need nesting, convert to YAML or TOML instead.

Is it safe to convert .env files with secrets?

Yes. The conversion runs entirely in your browser, so your .env data (including any secrets) never leaves your device.

What is ENV to JSON Conversion?

ENV to JSON conversion is the process of taking a .env file (the flat KEY=VALUE list almost every modern app uses for environment variables) and turning it into a structured JSON object. .env is dead simple by design; JSON is what APIs, debuggers, and most tooling actually consume. A env to json converter walks your dotenv file, parses each line, and writes the keys and values into a JSON object. You'll usually run a env to json conversion when you need to inspect a .env file, share config with a tool that only takes JSON, or feed environment variables into a script that expects structured input.

Why Convert ENV to JSON?

JSON is the universal format for APIs, browsers, and most modern programming languages. .env files, on the other hand, are designed for runtime config loading and don't lend themselves to validation or programmatic transforms. Converting env to json online lets you take that flat config and use it like data. Use a env to json tool when you need to validate a .env file's contents, share environment config with a teammate's JSON-based tool, debug an app's runtime config in a structured viewer, or generate JSON test fixtures from sample .env files.

How Our ENV to JSON Converter Works

When you click Convert, the tool parses your .env file line by line, splits each on the first equals sign, and writes the key-value pairs as a JSON object. Numbers and booleans are auto-detected so they end up as proper JSON types instead of strings. Quoted values (single or double quotes) are unwrapped to get the inner string. Lines starting with # are ignored as comments. Empty lines are skipped. Everything happens in your browser. Your .env data never leaves your device.

Features You Get

One-click conversion: hit Convert and the JSON appears in the output panel.
Type detection: numbers and booleans are auto-converted to their proper JSON types.
Quote handling: single and double-quoted values are correctly unwrapped.
Comment skipping: lines starting with # are ignored, just like dotenv loaders do.
Upload support: load a .env file from your device or drag-and-drop it into the input.
One-click copy: grab the JSON output with the Copy button and paste it anywhere.

How to Use the Tool

Paste your .env content into the input editor, or use the Upload File button to load a .env file.
Click the Convert button to generate the JSON output on the right.
Click the Copy button to copy the JSON to your clipboard.
Use the Clear button to reset both editors when you want to start over.

Common Use Cases

Config debugging: viewing .env contents in a structured JSON form to spot mistakes.
API hand-offs: sharing environment config with tools that only accept JSON.
Test fixtures: producing JSON samples from .env files for tests that read JSON.
Validation: loading .env into JSON Schema validators or other JSON-based linters.

Example Conversion

Input (ENV)

SERVER_HOST=localhost
SERVER_PORT=3000
DEBUG=true

Output (JSON)

{
  "SERVER_HOST": "localhost",
  "SERVER_PORT": 3000,
  "DEBUG": true
}
