Mailmerge.

For the basics, see:
Use mail merge for bulk email, letters, labels, and envelopes - Office Support
Mail merge using an Excel spreadsheet - Office Support
https://support.microsoft.com/en-gb/...-to-print-form

Word's mailmerge tools don't provide a separate document per record. To do that, see:
• Send Mailmerge Output to Individual Files; or
• Run a Mailmerge from Excel, Sending the Output to Individual Files,
in the Mailmerge Tips and Tricks thread 'Sticky' thread at the top of the Mailmerge forum:
