Frequently Asked Questions

Why convert from TOML to YAML?

While TOML is great for simple configurations, YAML offers more flexibility in data representation and is widely used in modern DevOps tools and cloud platforms. Converting to YAML can make your configurations more compatible with various systems.

What's the difference between block and flow styles?

Block style uses indentation to show structure and is more readable for humans. Flow style is more compact and uses braces and brackets similar to JSON, which can be better for machine processing or when space is a concern.

Are all TOML features supported?

Our converter handles most common TOML structures including nested objects, arrays, and basic data types. Some advanced features like dates and inline tables might need manual adjustment after conversion.

Is the conversion reversible?

While the core structure and data are preserved, the exact formatting might differ when converting back due to the different syntax rules of TOML and YAML. We recommend keeping a backup of your original files.
