VBA – VLookup with Multiple Criteria in Excel without Excel Formula but with VBA

|

VBA – Ubound of Multidimensional Array or How to Get What We Need?
Transforming Range to Array in VBA is actually a one liner – we take the range and we assign it to a variant:
|
1 2 3 4 5 |

Intersection of dictionary (or of any two lists) is a list with elements, that are present in both other lists. Thus, if we have the following 3 dictionaries in Python:
|
