Convert ENV to TOML - Complete Guide

Step 1

Input Your Environment Variables

Get your .env file ready. You have several convenient options:

•
Paste directly: Copy from your .env file or Docker Compose
•
Upload file: Click the Upload button to select your environment file
•
Try sample: Click the Sample button to see a working example

ENV format example:

DATABASE_HOST=localhost
DATABASE_PORT=5432
DATABASE_ENABLED=true
Step 2

Automatic Conversion to TOML

Watch as your ENV variables are transformed into TOML format. The converter provides:

•
Smart nesting: Reconstructs structure from underscore-separated keys
•
Type detection: Automatically detects numbers, booleans, and arrays
•
Modern config: Perfect for Rust and Python projects

TOML output example:

[database]
host = "localhost"
port = 5432
enabled = true
Step 3

Download or Copy Result

Once converted, download the TOML file or copy it to your clipboard. Perfect for migrating from Docker Compose to Rust projects.

FAQs About ENV to TOML Conversion

Why convert ENV to TOML?

TOML is more readable and powerful than ENV files. It supports nested structures, arrays, and comments natively. Converting from ENV to TOML allows you to modernize your configuration from Docker/.env files to Rust's Cargo.toml or other TOML-based configs.

How are underscores converted to nested structures?

Underscores in ENV keys are interpreted as nesting. For example, DATABASE_CREDENTIALS_USERNAME=admin becomes a nested structure: [database.credentials] with username = "admin".

Does it detect data types automatically?

Yes! The converter intelligently detects types: true/false become booleans, numeric values become numbers, and comma-separated values become arrays. Everything else is treated as a string.

Can I convert back to ENV?

Yes! Use our TOML to ENV converter to convert back. We also offer TOML Formatter, Validator, and converters for JSON, YAML, and XML.
