spread operator converting objects to array

I'm trying to convert a data structure like this:

data = { 
  0:{A:a}, 
  1:{B:b}, 
  2:{C:c}, 
}

into a structure like this:

[
 {0:{A:a}},
 {1:{B:b}}, 
 {2:{C:c}},
]

Using the spread operator like this: [...data] returns any empty array.

I also tried [{...data}]

Is there a way to use the spread operator to get the desired result? Also, why doesn't this approach work?
