Word Solution

I have a Word file with the mail merge function of Word gets quite a few points filled in by an Excel spreadsheet.

The Word has different paragraphs, which are not used with each form letter. The information if the paragraph is used is in the Excel file.
I need a solution that removes or hides the unused paragraphs in the Word file when Word is opened and takes the latest information from Excel.


Example of current status:
Article 1
Text with information from Excel
Article 2
Text with information from Excel
Article 3
Text with information from Excel

Example of what i want:
(Article 1 automated hidden/deleted based on Excel Information)
Article 2
Text with information from Excel
Article 3
Text with information from Excel
