I present the following situation.
1 - Draw polygon shape in QGIS 3.4 / geopackage, only with two columns ID and NUM_SETOR, using the google maps image as reference.
2 - Excel table where I combine a series of parameters, making use of formulas, dropdown list and free text. At the end I import this table into the QGIS.
3 - Make a JOIN between graphical feature (1) and table (2), having as a connection the columns NUM_SETOR.
4 - Export to a new shape.
I am trying to end using Excel and its formulas, making use of only the QGIS, for example, of the commands within the properties of the layer, attributes form -> Value Relation, Value Map, Data / time, etc. , creation of virtual fields for the concatenation of other fields, etc.
The problem is that everything is linked to the project and the layers being viewed. If I create a new project and connect to the same geopackage database, I will not have anything that I intend to do.
Is this the best way? Any suggestion? Can I reproduce all excel results in QGIS? I will try submit an example of the excel table.
