Any reason why this was closed?

I had overlooked that that setting already existed. My apologies.

I noticed that MC_GIVE_CMD is in nbt format and does not follow json format, so it cannot be saved as is as a json file. So I reopened this issue.

1. get a stone with this give command.

/give @s stone{display:{Name:"{\"text\":\"hogehoge\"}"}}

2. set copy format to MC_GIVE_CMD
3. copy the data of the stone

it results in this

{display:{Name:'{"text":"hogehoge"}'}}

It would be great if copy format setting had MINIFIED_JSON option. It allows to copy minified json
