TOML to YAML Converter

Convert TOML configuration files to YAML format seamlessly with structure preservation.

Loading...
1. Paste your TOML configuration content into the input area on the left side. 2. The tool validates the TOML syntax and reports any parsing errors. 3. View the converted YAML output with clean indentation and proper mapping structure in the right panel. 4. Verify that TOML tables and arrays of tables are correctly converted to YAML mappings and sequences. 5. Click the copy button to copy the YAML for use in your Kubernetes, Ansible, or GitHub Actions workflow.

About This Tool

The TOML to YAML Converter bridges two of the most popular configuration file formats used in modern software development. Convert your Cargo.toml, pyproject.toml, or any TOML configuration directly to YAML for use with Kubernetes, Ansible, GitHub Actions, and other YAML-based tools.

Both TOML and YAML are human-readable configuration formats, but they are used in different ecosystems. TOML is favored in Rust and Python tooling, while YAML dominates in DevOps, CI/CD, and container orchestration. This converter lets you move between these worlds without manual rewriting.

The tool first parses the TOML input, validates it, and then serializes the data structure as clean YAML. Tables become YAML mappings, arrays of tables become sequences of mappings, and all primitive types are properly represented. The output uses standard YAML formatting with consistent indentation.

Frequently Asked Questions

Common reasons include migrating configuration between ecosystems (e.g., from a Rust project config to Kubernetes), unifying configuration formats across a team, or preparing data for tools that only accept YAML input like Ansible or Helm charts.
Most types map directly. TOML integers become YAML integers, strings stay strings, and booleans remain booleans. TOML datetime values are represented as strings in YAML. TOML inline tables and regular tables both become YAML mappings.
Yes. The generated YAML follows the YAML 1.2 specification and is compatible with standard parsers. The output uses consistent indentation and avoids ambiguous syntax that could cause parsing issues.
Yes. Use our YAML to TOML Converter tool to perform the reverse conversion. Both tools are designed to produce clean, idiomatic output in the target format.
