Importing Data Into Word - But Eliminating Zero Value Lines

I've been asked to streamline some processes for a company I used to work with before I went on maternity leave (been two years now, my brain feels like its gone to mush). One of the things they have is a document where they input EVERYTHING manually into a word, sometimes the same thing several times. (felt like I had gone back into the dark ages). I know I can set up a template in Excel where all the required information can be imported into specific places within the word document, but Im struggling to find a solution to one part.

They get their clients to fill out an expenses form showing all their monthly expenses, some fields will be filled in but others are not relevant to them so they are left as zero.

How do I go about just importing ONLY the fields that have values input against them?

For example;

Mortgage $2000
Rent $0
Electricity $300
School Fees $0
Contents Insurance $200
Water $80
Pet Care $50
Groceries $1000
Takeaways $0

Then when the data is imported into word it would show up like this (formatted better of course)

Mortgage $2000
Electricity $300
Contents Insurance $200
Water $80
Pet Care $50
Groceries $1000
