Bulk import with json

Hi guys, I’m stuck and don’t know what to do :frowning: . I will be appreciate for any help.
I have the following problem.
I have a list of objects that are described with json file. And the corresponding static meshes in fbx and textures for them in tga.
The string in json looks like this
How can i bulk import and place all this objects into the scene. This json file consists of hundreds of static meshes, some are repeated several times.
So the second question is - how can I replace multiple static mesh objects with instance objects
Let’s imagine that i have 100 horrible static mesh trees placed all over my scene ( staticMeshActor1…100), how can i replace each of them with instanced mesh of a good static mesh tree ( i mean is there any way like in Maya, to select all the objects I want to be replaced and then select the object that I need to be placed, and then perform Replace Objects operation)

any clues, anything?

problem solved ))
