When preparing your resume, it’s common sense to prepare it in a Word format as it’s the standard. In addition, it’s helpful for the resume writing process, to make sure both grammar and spelling are correct.
However it is recommended to have your resume formatted as well in other formats such as text only and html. Having a text only version is indeed useful when it comes to copying and pasting your information in online resume application fields. As for having an html version of your resume, it allows you to publish it on any website.
