Frequently Asked Questions

How does type detection work?

When type detection is enabled, the converter automatically identifies numbers, booleans, and arrays in your CSV data. Numbers remain unquoted, booleans become true/false values, and array strings are converted to proper YAML arrays.

Which structure should I choose?

Array mode is ideal for collections of similar items where order matters. Object mode is better when you need to reference specific rows by key or when each row has a unique identifier. Both produce valid YAML but serve different use cases.

How are empty values handled?

Empty values in your CSV become null in the YAML output. You can also enable the trim option to remove unnecessary whitespace from values while preserving the actual data structure.

Is my data secure?

Yes, all processing happens entirely in your browser. No data is sent to any server, ensuring your CSV data remains private and secure throughout the conversion process.
