[
    {
        "data": [
            {

            },

i need a pipeline after that it should return array inside data as final result basically wanna get ride of outer array and curly braces

CodePudding user response：

You can use $unwind and $replaceRoot, like this:

db.collection.aggregate([
  {
    "$unwind": "$data"
  },
  {
    "$replaceRoot": {
      "newRoot": "$data"
    }
  }
])

Here's the playground link.
