URL for NFT

Hello,

I have a question. I am generating 5000 NFT with metadata in a json for each NFT.

And after that, I want to put these 5000 NFT on IFPS to have URL to put on the metadata of each json 5000 nft.

That is my question, i will have One URL by nft, so I will have to update one by one each 5000 json, it is too long. Do you do in other way ? Or with a script ? Could you help me please ? Thank you
