What TOML features are supported?

Standard TOML v1.0: key-value pairs, tables, inline tables, arrays, arrays of tables, integers, floats, booleans, strings (basic, literal, multi-line), and RFC 3339 date/time values.

Are TOML dates converted to ISO strings in JSON?

Yes. TOML datetime values (e.g., 2024-01-15T10:30:00Z) are converted to ISO 8601 strings in the JSON output.

Can I convert Cargo.toml and pyproject.toml files?

Yes. These are standard TOML files and the converter handles them fully. Paste the file contents directly — cargo and project metadata convert cleanly to JSON.

Does TOML support comments?

Yes. TOML comments (lines starting with #) are stripped from the JSON output since JSON does not support comments.

TOML to JSON Converter

Converts TOML (Tom's Obvious Minimal Language) files to JSON. Handles TOML tables ([table]), arrays of tables ([[array]]), inline tables, date/time literals, multi-line strings, and all TOML data types. Commonly used to convert Cargo.toml, pyproject.toml, and Hugo config files.

Runs entirely in your browser — your input is never uploaded, stored, or logged.

Paste your TOML configuration and get the equivalent JSON in seconds. For the reverse conversion, use the JSON to YAML tool to get YAML output from JSON.

Examples

Cargo.toml snippet

Input

[package]
name = "myapp"
version = "0.1.0"

Output

{"package":{"name":"myapp","version":"0.1.0"}}
