I write reports for a number of clients. I have a word document that is the template for these reports. I then fill in all of the clients details like name, address, license details etc, fill out tables, write some descriptions etc.

Is there a way to automate filling in some of the client details? I thought about making a seperate word document for each client but because I do minor updates regularly, this would require updating 30+ documents.

Thanks for any help you can provide.
