Frequently Asked Questions

What's the difference between YAML and TOML?

While both formats are used for configuration, TOML is more explicit and less prone to indentation errors than YAML. TOML uses explicit table headers and key-value pairs, making it easier to read and maintain for some use cases.

How are arrays handled in TOML?

TOML supports both inline arrays [1, 2, 3] and multi-line arrays. Arrays of tables use the [[table]] syntax. Our converter allows you to choose between inline and multi-line formatting for better readability.

When should I use equal sign alignment?

Equal sign alignment can make TOML files more readable when you have many key-value pairs with varying key lengths. It's particularly useful for configuration files that are frequently read or edited by humans.

How are dates handled?

TOML has built-in support for dates and times. The converter automatically detects date/time values and formats them according to the TOML specification. You can optionally quote date values for added compatibility.
