{"id":"**dad04f6d-4e06-4420-b0bc-cb2dcfee2dcf**","name":"new","url":"https://dev.azure.com/vishalmishra2424/82c93136-470c-4be0-b6da-a8234f49a695/_apis/git/repositories/dad04f6d-4e06-4420-b0bc-cb2dcfee2dcf","project":{"id":"82c93136-470c-4be0-b6da-a8234f49a695","name":"vishalmishra","url":"https://dev.azure.com/vishalmishra2424/_apis/projects/82c93136-470c-4be0-b6da-a8234f49a695","state":"wellFormed","revision":12,"visibility":"public","lastUpdateTime":"2021-04-22T14:24:47.2Z"},"size":0,"remoteUrl":"https://[email protected]/vishalmishra2424/vishalmishra/_git/new","sshUrl":"[email protected]:v3/vishalmishra2424/vishalmishra/new","webUrl":"https://dev.azure.com/vishalmishra2424/vishalmishra/_git/new","isDisabled":false}

The snippet you posted looks like JSON and a utility named file which can guess different types of file says that too:

$ file output.txt
output.txt: JSON data

You should use JSON-aware tools to extract value of id, for example jq:

$ jq -r '.id' output.txt
**dad04f6d-4e06-4420-b0bc-cb2dcfee2dcf**

or jshon:

$ jshon -e id < output.txt
"**dad04f6d-4e06-4420-b0bc-cb2dcfee2dcf**"
