How to find out unique value in each column in attribute table?
1) I am not fun of this ESRI's method ( professional GIS knowledge required + $$$$$ arcgis license) Identify duplicate or unique values in ArcGIS Pro https://support.esri.com/en-us/knowledge-base/how-to-identify-duplicate-or-unique-values-in-arcgis-pr-000023355
2) Google Map is idiot proof method without any gis software (no gis knowledge required, no $$$ required)
