    The second largest office software in the world after Microsoft Office

    Rebranded from Kingsoft Office in November 2016, WPS Office 2 was released in June 2020, making it an even more user-friendly office suite.
    Used by over 1 billion people worldwide, it has been the top-selling office software for consumers for 10 consecutive years. Not only can
    you view and edit Word, Excel, and PowerPoint documents created in Microsoft Office with WPS Office, but you can also output files to PDF .

Another plus is the solid support offered, unlike free versions. It's available for a 30-day free trial.
