What is TOML to YAML Converter?

TOML to YAML Converter is a free online tool that transforms TOML (Tom’s Obvious, Minimal Language) files into YAML (YAML Ain’t Markup Language) format. This converter handles complex nested structures, arrays, and various data types while preserving the hierarchical relationships between elements.

Key Features

Instant Conversion: Convert TOML to YAML in real-time with immediate results
Preserves Data Structure: Maintains hierarchical relationships and nested elements
Supports Complex Data Types: Handles arrays, tables, inline tables, and various scalar types
Client-Side Processing: All conversions happen in your browser with no data sent to servers
Copy to Clipboard: Easy one-click copying of the converted YAML output
Download Option: Save your converted YAML directly as a file

When to Use TOML to YAML Converter

This tool is particularly useful when:

Migrating configuration from TOML-based projects to YAML-based systems
Working with DevOps tools that require YAML instead of TOML
Converting configuration files for deployment pipelines
Translating documentation examples between formats
Learning the differences between TOML and YAML syntax

How to Use TOML to YAML Converter

Enter your TOML content in the input field or upload a TOML file
View the converted YAML in the output section
Copy the result to clipboard using the copy button
Download the YAML file if needed using the download button

Common Use Cases

Use Case	Description
Configuration Migration	Convert project configurations from TOML to YAML format for tools that require YAML
CI/CD Pipeline Setup	Transform build configurations for systems like GitHub Actions or GitLab CI
Docker Compose	Convert TOML configurations to Docker Compose YAML format
Kubernetes Manifests	Prepare Kubernetes resource definitions from TOML source data
Documentation	Generate YAML examples from existing TOML documentation

Advantages of YAML Over TOML

Wider Adoption: YAML is more widely supported in DevOps and configuration tools
Better Support for Complex Data: Native handling of complex data structures
References and Anchors: YAML offers anchor and alias features for reusing content
Multi-document Support: YAML can contain multiple documents in a single file

Limitations

While our converter handles most TOML features, be aware of these limitations:

Very large files may experience performance issues in browser-based conversion
Some TOML comments might not be preserved in the conversion process
Extremely complex nested structures might require manual verification

 FAQ

What's the difference between TOML and YAML?

TOML and YAML are both configuration file formats, but they differ in syntax and structure. TOML uses key-value pairs with explicit section headers (using square brackets), while YAML uses indentation to define hierarchy. YAML supports more complex features like anchors and references, while TOML is designed to be more straightforward and minimal.
Why would I need to convert TOML to YAML?

You might need to convert TOML to YAML when migrating between different systems or tools that support different configuration formats. Many DevOps tools, container orchestration platforms, and CI/CD pipelines use YAML as their standard format, so converting from TOML might be necessary when moving configurations between environments.
Can I convert large TOML files with this tool?

Yes, the tool can handle most common TOML files. However, very large files might experience some performance issues since the conversion happens in your browser. For extremely large files, consider using a command-line tool that runs locally on your machine.
Will the converted YAML have the same structure as my TOML file?

Yes, the converter preserves the hierarchical structure and relationships between elements in your TOML file. Tables in TOML become nested maps in YAML, arrays remain arrays, and scalar values retain their appropriate types. The main difference is in the syntax representation.
Does this tool send my data to any server?

No, this TOML to YAML converter processes everything locally in your browser. Your data never leaves your computer, making it safe for converting sensitive configuration files. All conversion logic runs as JavaScript in your browser.
What TOML features are supported by this converter?

The converter supports all standard TOML features including tables, inline tables, arrays, arrays of tables, and all primitive data types like strings, integers, floats, booleans, and dates. It handles nested structures and preserves type information when converting to YAML.
