Find Duplicate QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Identify duplicate and unique attribute values and create a documented Shapefile for spatial data-quality review.
About
Find Duplicate checks one selected key field in a point, line, or polygon layer and labels every feature as DUPLICATE IDENTIFIED or UNIQUE IDENTIFIED. The output keeps the key field and optional selected fields, adds frequency and location details, preserves the source geometry and CRS, and safely replaces an existing Shapefile only after the new output passes validation.
