What is TOML to YAML Converter?
Need to convert your TOML (Tom's Obvious, Minimal Language) configuration files to YAML (YAML Ain't Markup Language)? This tool converts TOML to YAML instantly. Perfect for converting TOML config files to YAML format for Docker Compose, Kubernetes, CI/CD pipelines, or any YAML-based system.
According to the TOML v1.0.0 specification, TOML is a configuration file format that's easy to read and write. YAML is widely used for configuration files, Docker Compose, Kubernetes manifests, and CI/CD pipelines. Converting TOML to YAML makes your configuration data accessible in YAML-based systems or applications.
Everything happens in your browser – your TOML never leaves your computer. Convert, download, and use your YAML file right away.
What Makes This Tool Different
Automatic Conversion
Paste TOML and get YAML instantly. We handle all the syntax differences – tables become YAML objects, arrays stay as arrays, everything gets converted correctly.
Structure Preservation
Your data structure stays intact. TOML tables, arrays, and all values are preserved exactly as they were in TOML.
Validation Built-In
We validate your TOML first, so you know the conversion will work. Invalid TOML gets caught before conversion starts.
File Upload Support
Got a big file? Just upload it. Works great for converting those massive TOML configs without copy-pasting.
Download YAML
One click to download your YAML file. Drop it into your project, use it in Docker Compose, Kubernetes, or any YAML-based system.
Syntax Highlighting
Beautiful syntax highlighting for both TOML input and YAML output. Visual feedback helps you verify the conversion looks right.
How It Works
Paste or Upload TOML
Paste your TOML into the left editor, or click "Upload" to load a file. You can also click "Sample" to see an example. The TOML should follow standard TOML syntax.
View YAML Output
Your TOML is automatically converted to YAML on the right. The YAML output appears instantly and is ready to use.
Copy or Download
Click "Copy" to copy the YAML to your clipboard, or "Download" to save it as a YAML file. The converted YAML is ready to use in your project.

Common Questions
Is my TOML data stored?
Nope. Everything happens right in your browser. Your TOML never leaves your computer – we don't even see it.
What TOML formats work?
The converter works with any valid TOML structure – tables, arrays, nested tables, and mixed types. It analyzes the structure and converts it to equivalent YAML.
How are TOML tables handled?
TOML tables become YAML objects. Arrays stay as arrays, and all data types (strings, numbers, booleans, dates) are preserved correctly.
Can I convert YAML back to TOML?
Yep. Use our YAML to TOML converter to convert YAML files back to TOML format.
What if my TOML has special characters?
Special characters are properly handled in YAML. Strings with YAML syntax characters are quoted or escaped correctly.
Does it work with large TOML files?
Yep. Since everything happens in your browser, it depends on your device. Small to medium TOML files convert instantly. Really huge files might take a few seconds.
