TOML to YAML

If your TOML input contains syntax errors, the converter may not be able to parse it correctly, and the conversion might fail or produce incorrect YAML. Ensure your TOML is valid before attempting conversion.

A TOML to YAML Converter is an online tool that transforms data structured in TOML (Tom's Obvious, Minimal Language) format into YAML (YAML Ain't Markup Language) format. This allows for easy conversion between these two popular configuration file formats.

Our converter parses the input TOML data, understands its structure (tables, arrays, key-value pairs), and then re-formats this structure into the equivalent YAML syntax. The conversion happens directly in your browser for speed and security.

You might need to convert TOML to YAML for several reasons:

• Interoperability: To use TOML configurations with systems that primarily support YAML.
• Readability: Some developers find YAML more readable for complex configurations.
• Tooling: Certain tools or libraries might have better support for YAML.
• Standardization: To maintain a consistent configuration format across a project or organization.

Using the tool is simple:

1. Paste your TOML content directly into the input text area.
2. Alternatively, you can upload a .toml file.
3. The tool will automatically convert the TOML data to YAML.
4. You can then copy the generated YAML output or download it as a .yaml file.

While the tool is designed to handle most common configuration file sizes, extremely large TOML files (e.g., many megabytes) might experience performance issues as the conversion is done client-side. For typical use cases, there should be no practical limit.

Yes, your data is safe. The conversion process is performed entirely within your web browser (client-side). Your TOML data is not uploaded or stored on our servers, ensuring your privacy and data security.

No, the conversion aims to preserve the semantic meaning of your data. The structure, data types (strings, numbers, booleans, arrays, tables/objects), and values are maintained. Only the syntax changes from TOML to YAML.

Key differences include:

• Syntax: TOML uses explicit syntax with sections ([table]) and key-value pairs (key = "value"). YAML relies on indentation to define structure and uses colons for key-value pairs (key: value).
• Complexity: TOML is designed to be minimal and obvious. YAML is more feature-rich, supporting anchors, aliases, and more complex data structures.
• Readability: Subjective, but TOML is often seen as simpler for basic configurations, while YAML can be more readable for deeply nested structures if formatted well.

This specific tool is designed for TOML to YAML conversion. For YAML to TOML conversion, you would need a different tool specifically built for that purpose.

Common use cases include:

• Migrating project configurations from TOML to YAML.
• Integrating applications that use TOML with systems that expect YAML.
• Using TOML for simpler parts of a configuration and YAML for more complex parts, requiring conversion for a unified view.
• Preparing data for tools that only consume YAML.

Typically, comments are not preserved during the conversion process as they are often considered non-essential for the data structure itself. The focus is on converting the data values and their organization.

Our converter aims to support the latest TOML specification. However, if you encounter issues with specific advanced or edge-case TOML features, please provide feedback so we can improve the tool.

This online tool is primarily designed for converting one TOML input (either pasted or uploaded) at a time. For batch conversions of multiple files, you might need to look for command-line tools or scripts.

Yes, this online TOML to YAML converter is completely free to use for all users.

Advantages of YAML can include:

• Better readability for complex, nested data structures due to its indentation-based syntax.
• Support for more advanced features like anchors and aliases, which can reduce redundancy.
• Wider adoption in certain ecosystems (e.g., Kubernetes, CI/CD pipelines).

Advantages of TOML can include:

• Simpler and more straightforward syntax, making it easier to learn and write for basic configurations.
• Less prone to errors caused by subtle indentation mistakes.
• Designed to be minimal and obvious, which can be beneficial for clarity.

The tool maps TOML data types to their corresponding YAML equivalents. For example, TOML strings become YAML strings, TOML integers become YAML integers, TOML arrays become YAML sequences (lists), and TOML tables become YAML mappings (objects/dictionaries).

Currently, the tool provides a standard YAML output format. Advanced customization options for the output, such as specific indentation levels or flow styles, are not available in this version.

If you encounter any problems while using the tool, or if you have suggestions for improvement, please feel free to contact us through our feedback channel. We appreciate your input to make the tool better!
