How can I create a document whose blanks are prefilled by the data in a spreadsheet?

How can I create a document whose blanks are prefilled by the data in a spreadsheet?

We plan on creating a Zoho Sheet with the following columns:
  1. Invoice Number
  2. Invoice Date
  3. Client's Name
  4. Client's address
  5. Services agreed to:
  6. Payment
  7. Total amount due
So for one row we would have something like:
  1. 262001
  2. July 20, 2012
  3. George Lincoln
  4. 21 Twilight Ave., Redmond, Texas, USA
  5. Assessment
  6. Check
  7. $2,000
How can we have a Zoho Doc (in Zoho Writer) that gets the info and prefills the blanks?

Google Docs can't seem to do this, and we hope Zoho or some other free online office suite can.

Thank you.
