JSON to CSV Converter That Handles Nested Objects

Converting JSON to CSV should be simple. Most tools choke on nested objects. Mine flattens them. Example Input: [ { "name" : "Alice" , "address" : { "city" : "NYC" , "zip" : "10001" } }, { "name" : "Bob" , "address" : { "city" : "LA" , "zip" : "90001" } } ] Output: name , address . city , address . zip Alice , NYC , 10001 Bob , LA , 90001 Nested objects get dot-notation column names.
