I have an excel with several rows and one column contains several lat/long for a polygon for each row. How to convert those lat/long of points into polygon?
e.g. one column contains
[100.61279296875, 13.9141845703125], [100.61279296875, 13.919677734375], [100.623779296875, 13.919677734375], [100.623779296875, 13.9141845703125], [100.61279296875, 13.9141845703125]
One solution is to wrap it up in some simple GeoJSON boilerplate and use the GeometryReplacer.
Let's say your column is called 'geometry'. Create a new attribute 'geojson' that has the following defintion (use the Text Editor):
{"type":"Polygon","coordinates":[[@Value(geometry)]]}Then pass it through a GeometryReplacer:
