TOML <-> YAML Converter

Convert TOML to YAML & YAML to TOML

This free online tool provides instant, bidirectional conversion between TOML and YAML configuration formats. The entire conversion process runs directly in your browser, ensuring your configuration files and sensitive data remain completely private and secure. Simply paste your TOML or YAML data into either editor to convert between formats in real-time.

How do I convert TOML to YAML?

To convert TOML to YAML, paste your TOML configuration into the code editor on giga.tools and click the convert button. The tool instantly parses your TOML file and displays the equivalent YAML structure with proper formatting and indentation. This is particularly useful when migrating configuration files between tools that require different formats, such as converting Rust project configs to Kubernetes-style YAML. If you need JSON format instead, our TOML to JSON converter can help.

How can I convert YAML to TOML?

Converting YAML to TOML is equally straightforward. Paste your YAML data into the editor, click the conversion button, and the tool will generate the corresponding TOML configuration. This is ideal when you need to create TOML configuration files from YAML sources used by Docker Compose, Kubernetes, or Ansible.

What is TOML format?

TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy to read and write. Created by Tom Preston-Werner, TOML uses a simple syntax with key-value pairs and supports complex data structures like arrays and nested tables. It's widely used in projects like Cargo (Rust package manager), Cloudflare Wrangler, Poetry (Python dependency management), and many modern configuration systems.

What is YAML format?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files. YAML uses indentation-based syntax to represent hierarchical data structures, making it popular in DevOps tools like Kubernetes, Ansible, Docker Compose, and CI/CD pipelines. It supports complex data types including nested objects, arrays, and multi-line strings.

Why convert TOML to YAML?

You might convert TOML to YAML when migrating projects between ecosystems or integrating with tools that require YAML format. For example, if you're deploying a Rust application to Kubernetes, you may need to transform your Cargo.toml configurations into YAML manifests. YAML's widespread adoption in cloud infrastructure and CI/CD makes this conversion valuable for cross-platform development.

Why convert YAML to TOML?

Converting YAML to TOML is useful when you prefer TOML's explicit syntax and stricter typing rules for configuration management. TOML's clear key-value format can be easier to edit than YAML's indentation-sensitive syntax, reducing configuration errors. This is particularly beneficial for application settings, environment configurations, and package management files. For working with YAML and JSON formats, check out our YAML to JSON converter.

Is this TOML <-> YAML converter safe for sensitive data?

Yes, this converter is completely secure for sensitive configuration files. Since all conversion logic runs entirely within your browser, your data is never uploaded to any server or transmitted over the internet. Your API keys, credentials, database passwords, and private configurations remain on your local machine throughout the conversion process.

Does this tool validate TOML and YAML syntax?

Yes, the converter automatically validates both TOML and YAML syntax during conversion. If your input contains syntax errors—such as invalid TOML tables, incorrect YAML indentation, or malformed data types—the tool displays a clear error message to help you identify and fix the problem. This makes it function as both a converter and a validator for configuration files.

Is this TOML to YAML converter free?

Yes, the TOML <=> YAML converter on giga.tools is completely free to use. There are no sign-ups, subscriptions, usage limits, or hidden fees required to convert between TOML and YAML formats. You can use it as many times as needed for both personal and commercial projects.
