什么是.env转JSON转换器？
The .env to JSON Converter is a free online developer tool that instantly converts .env file content into JSON format. It automatically parses KEY=VALUE pairs, handles comments (lines starting with #), strips quotes from values, and supports multiline values. Perfect for developers who need to convert environment configuration files to JSON for API configs, Docker Compose, or deployment tools. All conversion happens locally in your browser — no data is ever uploaded to a server.
核心功能
- Smart Parsing: Handles KEY=VALUE pairs, inline comments, empty lines, and various value formats
- Quote Handling: Automatically strips single and double quotes while preserving inner quotes
- Auto Type Detection: Numbers, booleans, and null values are auto-detected and converted to proper JSON types
- Prefix Grouping: Optionally group variables by common prefix (e.g., DB_HOST, DB_PORT → {DB:{HOST:...,PORT:...}})
- 历史记录: Auto-saves last 5 conversions
使用方法
1. Paste .env content into the input area, or click "Load Example".
2. Set options: auto type detection, prefix grouping, include comments.
3. Click "Convert" or use Ctrl+Enter.

技术背景
The .env file format is a de facto standard for environment variable configuration, popularized by Node.js dotenv library. Each line contains a KEY=VALUE pair, with # for comments. Values can be quoted with single or double quotes to include spaces or special characters. The format supports variable expansion ($VAR or ${VAR}) in some implementations. JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for configuration management in modern cloud-native applications.
