What is TOON to TOML Converter?
Need to convert your TOON format (Token-Oriented Object Notation) data to TOML format? This tool converts TOON to TOML instantly. Perfect for configuration files, package managers, or any system that uses TOML.
TOML (Tom's Obvious, Minimal Language) is a configuration file format that's easy to read and write. It's used by many modern tools like Cargo (Rust), Poetry (Python), and others. Our converter decodes your TOON data and transforms it into properly formatted TOML with correct syntax, tables, and values.
Everything happens in your browser – your data stays private. You can also validate your TOON first using our TOON Validator or convert it to JSON with our TOON to JSON converter.
What Makes This Tool Different
Valid TOML Syntax
Generates valid TOML that follows TOML v1.0.0 specification. Proper tables, key-value pairs, and structure ensure compatibility with any TOML parser.
Human Readable
TOML output is clean and readable with proper formatting. Easy to read, edit, and understand – perfect for configuration files that humans need to maintain.
Type Preservation
Strings, numbers, booleans, arrays and nested objects map to their TOML equivalents, and long integers keep every digit. TOML has no null, so null values are left out and listed in a comment at the top.
File Upload Support
Got a TOON file? Just upload it. Works with .toon and .txt files. No need to copy-paste – just drag and drop or click upload.
Download TOML
One click to download your converted TOML as a .toml file. Perfect for saving, sharing, or using in TOML-based configuration systems.
Nested Tables
Handles complex nested structures perfectly. Objects become TOML tables, nested objects become nested tables, and arrays are converted correctly.
How It Works
Paste or Upload TOON
Paste your TOON data into the left editor, or click "Upload" to load a file. You can also click "Sample" to see example TOON format. The tool accepts any valid TOON structure.
Automatic Conversion
As soon as you paste, the converter processes your TOON and displays the converted TOML on the right. Arrays become TOML arrays, objects become tables, and values are properly formatted.
Copy or Download
"Copy" puts the TOML straight onto your clipboard; "Download" writes it out as a .toml file instead. The TOML is properly formatted and ready to use in any TOML-compatible system.
When You'd Actually Use This
Package Managers
Working with Rust's Cargo, Python's Poetry, or other tools that use TOML? Convert TOON data to TOML for use in Cargo.toml, pyproject.toml, or other package configuration files.
Application Configuration
Many modern applications use TOML for configuration files. Convert TOON data to TOML for use in application settings, deployment configs, or environment configurations.
Build Tools
Using build tools that prefer TOML format? Convert TOON to TOML for use in build configuration files, CI/CD settings, or deployment scripts.
Data Migration
Migrating data to systems that require TOML format? Convert TOON to TOML for use in configuration-driven applications or TOML-based data stores.
Common Questions
Is my TOON data stored?
No. All conversion happens in your browser using the @toon-format/toon library and smol-toml. Your data never leaves your computer.
What TOON formats are supported?
We support all valid TOON formats according to the TOON specification. Arrays, objects, tabular data, nested structures, primitives – everything that TOON supports.
Is the TOML valid?
Yes, the output is written by smol-toml and follows the TOML 1.0 rules. Anything TOML can't express, like null, is left out and listed in a comment at the top rather than written as invalid TOML.
How are data types handled?
Strings, numbers and booleans map straight across, objects turn into TOML tables, and a list of objects is written as an array of tables. Two things TOML can't do: there is no null (those keys are left out and named in a comment), and the top level must be a table, so a TOON document that is just a list or a single value gets a clear error.
Can I convert TOML back to TOON?
Yes. First convert TOML to JSON using our TOML to JSON converter, then convert JSON to TOON using our JSON to TOON converter.
Does it work with large datasets?
Yes. Since everything happens in your browser, it depends on your device. Small files convert instantly. Very large files (10MB+) might take a few seconds, but they'll still work.
Other TOON Tools You Might Need
Converting TOON to TOML is just one TOON task. Here are other tools that work well together:
