TOML to YAML is a free online converter on AltFTool that converts TOML configuration into readable YAML for infrastructure and app config workflows — no signup and nothing to install.
The conversion runs entirely in your browser: the TOML you paste is converted on your own device and is never uploaded to AltFTool. TOML to YAML is powered by the @iarna/toml library, and the YAML result can be copied or downloaded as toml-to-yaml.yaml.
| Input format | TOML |
|---|---|
| Output format | YAML |
| Output file | toml-to-yaml.yaml (text/plain) |
| Runs | In your browser — the input is not uploaded. |
| Library | @iarna/toml |
| Category | Others converters on AltFTool |
Open TOML to YAML on AltFTool — the converter loads straight away, with no account.
Paste your TOML into the left-hand input pane, or press Sample to load a working example.
The conversion runs automatically about 300ms after you stop typing — there is no Convert button, and nothing is uploaded while it works.
If this converter exposes options, open Settings to change them — the output re-runs as you adjust.
Copy the YAML output with the Copy button, or download it as toml-to-yaml.yaml.
No. TOML to YAML runs entirely in your browser using the @iarna/toml library, so the TOML you paste is converted on your own device and never reaches AltFTool's server.
The @iarna/toml library, running in your browser. The YAML you see is that library's output rather than an approximation written here.
There is no server-side limit, because nothing is uploaded — TOML to YAML converts in your browser, so the practical ceiling is your own device's memory.
The result is YAML. Copy it from the output pane in one click, or download it as toml-to-yaml.yaml — AltFTool names the file after the converter and serves it as text/plain.
Yes. TOML to YAML is free to use on AltFTool, with no account and no sign-up.
Drop the live TOML to YAML workspace into your own docs page, tutorial or blog post with one snippet. Free, responsive, light and dark — just keep the “Widget by AltFTool” credit link visible.
