npm audit response shows up as just plain text instead of tabular format

Question

I read a lot of questions/articles related to npm audit where people have provided the response of the npm audit in a tabular format. But when I run the npm audit I get the response as plain text.

I tried to install a library npm-audit-html and get the format in HTML as provided in answer but that is running into the issue: zsh: command not found: npm-audit-html

Can someone please explain and help in resolving the beautification of the npm audit response? Currently, my npm audit response shows up something like this:

Answer 1

In windows, I've used npm audit with ">" to write its content in a json file, refer below command:

npm audit --json > FOLDER_PATH\FILE_NAME.json

Answer 2

The npm audit format you posted is a breaking change of npm 7.

Output and data structure is significantly refactored to call attention to issues, identify classes of fixes not previously available, and remove extraneous data not used for any purpose.

BREAKING CHANGE: Any tools consuming the output of npm audit will almost certainly need to be updated, as this has changed significantly, both in the readable and --json output styles.

As the output format not officially explained, there is a post try to find it out. You can check the post for more details.
