As @dandavis says, I think you can do element.innerHTML to preserve formatting if what you mean by formatting is: list, font weight, font size, etc.
For example, for this page: https://www.linkedin.com/jobs/collections/hiring-in-network/?currentJobId=4093133656
I can do document.querySelector('article').innerHTML to obtain the job description with it's format as shown here:
<div class="jobs-description__content jobs-description-content
">
<div class="jobs-box__html-content

jobs-description-content__text--stretch" id="job-details" tabindex="-1">
