Hello Tabitha,
Trial installations are time bond installations, which go into the Reduced Functionality Mode (RFM) after the trial period is over. Once the
trial period is over, there is no way to extend the trial.
As a workaround, you may use Office Web Apps to edit and create files. To know more on Office Web Apps, refer to the following link:

I hope the above information helps. If you still have questions, you can always reply and I’ll be happy to assist you.
Thank you
