Attributes and final meta clean up

[Shasti001]

Currently the meta is written as follows

{
"name": "Project name",
"description": "Project description.",
"image": "URL",
"dna": "#",
"edition": # ,
"date": #,
"attributes": [
{
"trait_type": "Value",
"value": "Vale"
},
{
"trait_type": "Value",
"value": "Vale"
},
"trait_type": "Value",
"value": "Vale"
}
]
}

My ask is how would you get the meta cleaned to be written like below. So removing the attributes just having the trait and value.

"Item#": {
    "trait": "value",
    "trait": "vlaue",
    "trait": "value",
    "trait": "value",
    "image": "ipfs://",
    "mediaType": "image/png",
    "name": "ItemName",
  }
}

}
}

you would need the original metadata exported for ETH and then run a custom script to reformat it. What metadata standard is this for?
