I need help populating a Word table based on data in Excel.

I have inherited a spreadsheet that documents when volunteers are available to attend certain sessions, cells are marked with Y,N and USE depending on whether someone is available or not and whether they are being used. 

I need to be able to send the volunteers a document listing which sessions they should attend.

My predecessor typed each document individually but with potentially up to 40 volunteers doing up to 10 sessions each there must be a better way can any one help? 

I've attached the Excel document as well as the word document that has previously been used, It doesn't have to be exactly the same but it needs the same info.
