Control which document regions are editable based on user permissions from Word permission ranges. When a Word document contains permission ranges (w:permStart/w:permEnd), SuperDoc automatically restricts editing to the allowed regions for the current user.

​
How it works

Permission ranges define editable regions within a protected Word document. The extension:
  1. Parses permStart and permEnd markers from the document
  2. Matches the current user’s email against the ed (specific editor) or edGrp (editor group) attributes
  3. Allows edits only within matched permission ranges
  4. Blocks edits outside permitted regions
When a document is in viewing mode and has permission ranges matching the current user, the extension automatically enables editing within those ranges.

​
Permission matching

Ranges can target specific users or groups: 
<!-- Allow everyone to edit -->
<w:permStart w:id="0" w:edGrp="everyone"/>
<w:permEnd w:id="0"/>

<!-- Allow a specific user -->
<w:permStart w:id="1" w:ed="domain\username"/>
<w:permEnd w:id="1"/>
The ed attribute uses the format domain\username, matched against the user email configured in SuperDoc.

​
Word export

Permission ranges export as native Word permission markers: 
<w:permStart w:id="0" w:edGrp="everyone"/>
<w:r>
  <w:t>Editable content here</w:t>
</w:r>
<w:permEnd w:id="0"/>
