Frequently Asked Questions

What TOML features does the JSON ⟷ TOML Converter support?

The converter supports the full TOML v1.0 specification including tables, array of tables, inline tables, multiline strings, and all value types such as string, integer, float, boolean, and datetime.

How do I switch between JSON to TOML and TOML to JSON conversion?

Use the direction toggle buttons at the top of the editor. Click JSON → TOML to convert JSON input into TOML output, or TOML → JSON to parse TOML input and produce JSON output.

Can I customize the JSON output formatting?

Yes, you can choose from four indentation options: 2 spaces, 4 spaces, tab, or minified. The indent setting applies to the JSON output when converting from TOML to JSON.

Does the converter handle nested objects and arrays correctly?

Yes, the converter fully supports nested objects, arrays of primitive values, and arrays of objects (mapped to TOML array of tables). Complex structures with deeply nested tables are converted accurately in both directions.

Is my data safe when using the JSON ⟷ TOML Converter?

Absolutely. All processing happens locally in your browser. No data is uploaded to any server, ensuring your information remains completely private and secure.
