DataWeave Delight: Using pluck function to transform object to array Posted on June 10, 2022 by Hubert Klein Ikkink DataWeave Sometimes we get a data structure with keys and values and we want to create an array with data from the data structure. This example uses the core Dataweave function pluck;it is useful in mapping an object into an array, pluck iterates over an object and returns an array of keys, values, or indices from the object. We have a handle on all data to pluck the information and transform it to elements in an array.

Youll have to use the explicit lambda in order to do that. It returns an empty array when n <= 0 You'll notice that the reduce function has the signature (':array', ':function') => ':any'. If you are only interested only in the contents of the array then you can use the DataWeave expression payload.Person which will return ["sri", "123456","India"], which is a valid array in JSON. In the following examples we have object structure with keys book1 and book2 that we want to transform to an array. In this case, since were only using v and k we can also use the following code: Finally, here is how the previous code would look like with the dollar-sign syntax: You need to surround the k (or $$) parameter in parentheses to correctly reference the value of the index when using it as a Key. Find centralized, trusted content and collaborate around the technologies you use most. While not required to follow this tutorial, a good understanding of the basic DataWeave concepts would be preferred. They are: What I mean is this: if you know a transformation is going to modify values in an array and return an array you'd probably reach for map first, if you know a transformation is going to modify values of an object, and return an object, you'd reach for mapObject first, etc. pluck is commonly used in conjunction with groupBy.
