Getting attributes from Decode Json file

I have this Terraform code that decodes a JSON and CSV file.

provider "azurerm" {
    features{}
}

locals {
      resource_groupname = csvdecode(file("./ResourceTypes.csv"))
      json_data = jsondecode(file("${path.module}/Monitor.json"))
    }

    resource "azurerm_resource_group" "Main" {
      count    =  length(local.resource_groupname)
      name     =  local.resource_groupname[count.index].resourcetype
      location = "North europe"
    } 
     resource "azurerm_resource_group" "name" {
       # (other settings)
       name = local.json_data.name
       location = "North europe"
     }

      output "local_json_data" {
        value = local.json_data
      } 

when I run the terraform code I have the output as below

  # azurerm_resource_group.Main[212] will be created
  + resource "azurerm_resource_group" "Main" {
      + id       = (known after apply)
      + location = "northeurope"
      + name     = "Wandisco.Fusion"
    }

  # azurerm_resource_group.name will be created
  + resource "azurerm_resource_group" "name" {
      + id       = (known after apply)
      + location = "northeurope"
      + name     = "Azure-APIManagement-FailedRequests"
    }

Plan: 214 to add, 0 to change, 0 to destroy.

Changes to Outputs:

    }

Is there a way I can hold the attributes from the JSON and CSV file, and save it to a variable as a string in terraform? and then make a new terraform script from the variables?

My end goal is to try and create a terraform script from a JSON file.
