from an array of objects, how to create a new object array where each item would take the key of the previous array?

I have an array of objects each containing between one and more items. how to create a new object array where each item would take the key of the previous array? I tried to extract the key with object.keys and code something but for more than 2 hours I am completely stuck, I am not achieving the expected result.

What methods could I use?

Edit, the last thing I tried :

Object.entries(categories).forEach(([key, value]) => {     const k = Object.keys(categories).find(key => categories[key] === value);     array.push({ [k]: value });   });  

INPUT

[    { "shopCategory": { "shop1": "object" } },    { "placeCategory": { "place1": "object", "place2": "object" } },    { "sellerCategory": { "seller1": "object", "seller2": "object", "seller3": "object" } }  ]  

OUTPUT

[    { "shopCategory": { "shop1": "object" } },    { "placeCategory": { "place1": "object" } },    { "placeCategory": { "place2": "object" } },    { "sellerCategory": { "seller1": "object" } },    { "sellerCategory": { "seller2": "object" } },    { "sellerCategory": { "seller3": "object" } }  ]
