I have a sheet with the column with polygon information in WKT format. However, the data taken are from web mapping (OSM or google maps) and in the order of lat, lng. When I am using the solution from this thread (Visualising WKT geometry string in QGIS) which are what I need, I do not have another choice to switch x and y other than manually. But concerning the number of data, I need to find something more efficient.
Basically my polygon data is in the format
55.947686 -3.132133, 55.945932 -3.131232, 55.947878 -3.121362, 55.943168 -3.117714, 55.943841 -3.108273, 55.94771 -3.108745, 55.950161 -3.119216
but I need -
-3.132133 55.947686, -3.131232 55.945932, ....
There are so many items in the dataset so manual transfer is not an option.
Is there a tool somewhere (even outside QGIS environment) to do it for me?
