Typically when people put in requests like this without providing a realistic sample document, the initial solutions don't fit because of things that aren't said. If you provided a sample doc you would get a much better solution since we can test the macro without having to make assumptions.
The specific questions I would need answered first are:
- Do your tables contain any merged cells?
- Your text says add 'english' to column 3 but your screenshot shows it in column 10. Which is correct?
- Does the c./v. replacement happen anywhere in the row or only in a specific row?
- Does the c./v. replacement happen only when there is a space in front of the c.?
