I have a Google Doc with tons of hyperlinks within various text strings throughout the document. All the links have the same root URL (say, my.oldsite.com). Recently the site changed their root URL to my.newsite.com and now I need to change all the links to the new root. So I want to FIND 'my.oldsite.com' and REPLACE with 'my.newsite.com'. The built-in Find and Replace is not working for me, hoping someone knows a way.
There is no way to do it natively in Google Docs. Maybe you should use a Docs add-on that could do it.
This add-on allows you to do it (Link URL and Set Link URL) but it is not free, though it is only $5: Advanced Find & Replace
