JSON TO YAML conversion

Hello Everyone,

I am new to the swagger platform. So this might be a very basic question but I am not able to achieve this so please help me with this.

Question:  I want to convert the JSON to YAML with valid data types so that I can copy-paste and use it.  Else can someone guide how we can put the JSON in the definition? 

I tried the online tool to convert but the tools are not adding the data type so without data type swagger is not saving my code.
