Transform arrays to objects

This article explains how you can change arrays to an array of objects

Let's say, you want to change the following data from arrays to objects:

{
  "categories": [

{
  "categories": [
    {
      "name": "concrete"
    },
    {
      "name": "posts"
    },
    {
      "name": "system"
    }
  ]
}

1. Create a new Transformer. Use Data, transform data using mappers and conditions
2. Choose Move using a pattern
3. Fill in the Pattern categories
4. Fill in the Replacement result.categories.$1.name

And you're set!
