Hi, I have read this documentation, but not sure it addresses this - is there a way to use triangles already formatted in excel/csv as a triangle (not flat database) in CL python package? I can of course import them as data frames, but I want them to be triangle objects to use the triangle methods

The package currently requires data to be tidy/long format when making a Triangle. If your data is already in the form of a triangle shape, you can refer to #218 on an example on how to adapt it.
