What is the Structured Data Viewer?

The GoChronos Structured Data Viewer lets you paste or upload JSON, YAML, TOML or XML and instantly visualise it as a collapsible tree, validate it for syntax errors, convert between formats and copy a prettified version.

What is the difference between JSON, YAML and TOML?

JSON is a lightweight data-interchange format widely used in APIs. YAML is a human-readable superset of JSON often used for configuration files. TOML is a minimal config format designed to be unambiguous and easy to parse, used by Rust's Cargo and many CI systems.

Can I convert between JSON, YAML and TOML?

Yes. The Structured Data Viewer imports any supported format and exports to any other. For example: paste YAML and download it as JSON, or paste TOML and download it as YAML.

Is the structured data viewer free?

Yes. Completely free, no account required, works offline after the initial page load.
