Working with YAML Data

Handling Nested Structures

YAML often contains nested structures. Our converter provides options to either flatten these structures using dot notation (e.g., "team.lead") or preserve them as JSON strings. This flexibility allows you to choose the most readable format for your needs.

Array Handling

Arrays in YAML can be handled in two ways: joined into a comma-separated list or expanded into individual columns. The "Join Arrays" option lets you control this behavior, making it easy to represent lists in the way that best suits your data.

Type Preservation

When enabled, the "Preserve Data Types" option maintains the original data types (numbers, booleans) in the output. This is particularly useful when the table will be processed further or when precise type information is important.

Frequently Asked Questions

How are nested YAML structures handled?

By default, nested structures are flattened using dot notation (e.g., "parent.child"). You can disable this behavior to keep nested structures as JSON strings in the table. This gives you flexibility in how you want to represent complex data structures.

What happens to arrays in YAML?

Arrays can be either joined into a comma-separated list or expanded into individual columns, depending on your preference. This is controlled by the "Join Arrays" option, allowing you to choose the most appropriate representation for your data.

Is my data secure?

Yes, all conversion happens entirely in your browser. Your YAML data is never sent to any server, ensuring complete privacy and security of your information.

Can I process large YAML files?

Yes, the converter can handle large YAML files, though processing time may increase with file size. Since all processing happens in your browser, the practical limit depends on your device's capabilities.
