Excel to word link?

Is there a way to link excel to word documents?

i do a lot of proposal writing and each time i have to fill out an excel sheet w the project information,

then when writing the proposal i end up repeating that same information so many times on word.

is there a way to create something to link the two templates so that the box where i input the client name is pasted to multiple places on the word document, and etc (like box 4A pasted to a few places in the word document, the box 7A is pasted to its counterpart places and so on?)
