Eight years ago, Microsoft turned Office into a subscription service . In July 2017, it announced that Office 365 revenue had surpassed that of previous versions. Then, in October 2017, the company predicted that two-thirds of Office users would be in the cloud by next summer.
However, if you wish to use Office 365 without paying for it, there are solutions.

Free online Office applications
At this link you can use limited functions of the most classic Office online and for free.
As you can imagine, Microsoft 's offering comes as a response to the ever-evolving Google Docs.
Free Office applications for mobile
If you're using a phone or tablet, you can get the corresponding version of Office for free here. They're great versions of the Office apps with minimal limitations.
As a note here we should mention that if your screen is larger than 10.1 inches you will have to pay the Office 365 subscription as usual.
Educational editions
If you are a student or teacher you can obtain the full version of Office 365 for free, provided that the organization you belong to has purchased the corresponding educational license.
Trial version
If you don't need Office for everyday use, but perhaps a Powerpoint or for a task in Excel, the trial version is exactly what you need.
Among the disadvantages here we must mention that you are required to provide your credit card to Microsoft and remember to cancel the trial period before the first month ends, otherwise it will turn into a one-year subscription for Office 365 Home edition.

Try again
There have been reports, apparently against the terms of use, of people using different email and credit cards to get another free month of Office 365.
Try again and again
There is a second legal way to get a 30-day trial version of Office that is primarily aimed at potential corporate uses
If you are approved for the corporate trial of the product, you can share the license with 25 more people.
Free with the purchase of a computer
It sounds a bit counterproductive but if you happen to be looking for a computer, there are multiple offers that include a free usage period of Office 365.
