Use CSV to YAML

Convert CSV records into a YAML sequence while preserving every cell as a string. Start with the sample, select the options and run the tool. Copy or download the result after reviewing it.

Behavior and limits

Headers become mapping keys and each CSV data row becomes a sequence item. Values such as true, 007 and large IDs stay strings rather than being inferred as booleans or numbers. Duplicate and blank headers receive unique names.

Example input

name,enabled
Ada,true
Lin,false

Expected behavior for the example

A YAML sequence with two mappings; enabled values remain quoted strings.

Check important output in the application that will consume it. Use the tool directory to find related formats and tasks.
