Frequently asked questions

Can Word add-ins work with tracked changes?
Yes, we can develop logic that interacts with Word's review features, including comments and tracked changes, for automated document reviews.
Can we restrict editing to certain parts of a document?
Absolutely. Using Content Controls and add-in logic, we can create 'guided' documents where users can only edit specific fields.
