How to EASILY CONVERT an OLD WORD Document to a NEWER Version! (& Unlock New Features)
To use the modern features of Word 2019 or Office 365, you should upgrade your Word documents if they're based on an older version of Word software. Upgrading ensures that your documents are compatible with newer versions of Word and that you can use the new formatting and other tools that are available in the latest versions of the software.
Converting an old Word document to a newer version only takes a few clicks, as long as you have Word software installed on your computer. Once the file is converted, you will see that it has a new extension that only newer Word files use.
If you have the Microsoft Office suite installed on your computer, you probably also have Word installed. You can use this software without the need for add-ons to upgrade your Word documents.
