Is the toml to yaml converter free?

Yes, completely free. No sign-up, no daily limit, no watermark on the output.

Are TOML data types preserved?

Yes. Numbers, booleans, strings, arrays, dates, and nested tables all keep their types in the YAML output.

How are TOML tables converted?

Tables and subtables become indented YAML mappings, preserving the original structure.

Does the converter support arrays of tables?

Yes. Arrays of tables ([[items]]) become YAML lists with each entry as a dash-prefixed block.

Are TOML comments preserved?

No. Comments are dropped during conversion since they don't map cleanly between TOML and YAML.

Is the conversion private?

Yes. Everything runs in your browser, so your TOML data never leaves your device.

What is TOML to YAML Conversion?

TOML to YAML conversion takes a TOML config file and rewrites it as YAML, the indented format used by Kubernetes, Docker Compose, GitHub Actions, and most modern config tools. TOML uses sections in square brackets and explicit equals signs; YAML uses indentation and dashes for lists. A toml to yaml converter walks your TOML and writes the same data with YAML's cleaner, indentation-based syntax. You'll usually run a toml to yaml conversion when you're moving a TOML config into a tool that prefers YAML.

Why Convert TOML to YAML?

YAML has quietly taken over DevOps. Kubernetes, Helm, GitLab CI, GitHub Actions, CircleCI, Ansible, and most container orchestration tools use YAML by default. TOML, on the other hand, is the format of choice for human-edited config in Rust and Python projects. Converting toml to yaml online lets you bridge those worlds. Use a toml to yaml tool when you need to migrate a TOML config into a Kubernetes or Helm setup, generate YAML examples for docs from TOML samples, hand off settings to a team using YAML pipelines, or modernize older TOML configs into a format that fits DevOps workflows.

How Our TOML to YAML Converter Works

When you click Convert, the tool parses your TOML, then writes it out using YAML's indentation rules. Strings stay strings, numbers stay numbers, booleans stay booleans, and ISO dates remain dates. TOML tables become indented YAML blocks. Arrays of tables ([[items]]) become YAML lists with dash-prefixed entries. The output uses two-space indentation (the YAML standard) so it loads cleanly in any YAML parser. Everything runs in your browser. Your TOML data never leaves your device.

Features You Get

One-click conversion: hit Convert and the YAML appears in the output panel.
Type-aware output: numbers, booleans, dates, and strings each keep their proper types.
Nested table support: TOML sections and subtables become indented YAML mappings.
Array of tables support: [[items]] blocks become YAML lists with the right structure.
Upload support: load a .toml file from your device or drag-and-drop it into the input.
One-click copy: grab the YAML output with the Copy button and paste it into your config file.

How to Use the Tool

Paste your TOML into the input editor, or use the Upload File button to load a .toml file.
Click the Convert button to generate the YAML output on the right.
Skim the result. YAML being indented makes structure mistakes obvious fast.
Click the Copy button to copy the YAML to your clipboard.

Common Use Cases

Config migration: moving TOML configs into Kubernetes, Helm, or CI YAML.
Documentation: generating readable YAML examples for docs from TOML samples.
DevOps modernization: transforming TOML settings into YAML the team can edit in pipelines.
Cross-team hand-off: sharing config with teams that work in YAML, not TOML.

Example Conversion

Input (TOML)

[server]
host = "localhost"
port = 3000
features = ["auth", "billing"]

Output (YAML)

server:
  host: localhost
  port: 3000
  features:
    - auth
    - billing
