If I had a data class that looks like data class Sample(val foo: Number) and the following example map that I may not know until runtime mapOf("foo" to 1, "bar" to 2, "baz" to 3) . How can I extract just the value that's relevant to the Sample data class and build it when I don't know if the field in question will be present?

if jackson's objectmapper is an option it's as simple as

ObjectMapper().convertValue<Sample>(map)

You could delegate that property to the map https://kotlinlang.org/docs/reference/delegated-properties.html#storing-properties-in-a-map

or use one of the options described here https://stackoverflow.com/questions/51898966/convert-a-map-to-a-data-class
