I have my meta data in a generation format. However I need to load it to a data base using Parent child hiearchy.

Generation 1 Generation 2 Generation 3 Generation 4
The World Europe Sweden Stockholm
The World Europe Sweden Gothenburg
The World Europe Norway Oslo
The World Asia Thailand Bangkok
The World Asia Japan Tokyo

So I want to convert this data to:
Parent Child
The World
The World Europe
The World Asia
Europe Sweden
Europe Norway
Asia Thailand
Asia Japan
Sweden Stockholm
Sweden Gothenburg
Norway Oslo
Thailand Bangkok
Japan Tokyo

Is there an easy method to do this.
The opposite can be done with ease in PowerPivot using Dax (using Path, Pathlength and, pathitem formulas) as described e.g. here https://www.daxpatterns.com/parent-child-hierarchies/
If there is an easy way to do this in PowerQuery or PowerPivit or if anyone have a macro where I can define number of levles in the generation hiearchy I would highly appreciate if you could share it with me.

Workdays for a market open Mon, Wed, Friday?
Yes! Use "0101011" for the weekend argument in NETWORKDAYS.INTL or WORKDAY.INTL. The 7 digits start on Monday. 1 means it is a weekend.

Hey Mick!

Thanks for your response.

Script works as per my problem description.

However, I wonder if you can do a few modifications to it.

1. I want Parent and child to be in 2 separate columns and also in a new worksheet instead of a specific cell on existing worksheet. The reason is that number of generations varies between my tables, think the biggest one has 16 generations.

2. I want to be able to specify which columns the macro should apply to. normally I have some a sort column after each generation and quite often a descriptive text
If the macro could be set up something like this.

Gen1 = Range A
Gen2 = Range C
Gen3 = Range E
Gen4 = Range H
Gen5 = Range ""
Gen...
Gen20 = Range ""

Where Range (A;C;E;H) are the columns that should be included and Range "" can be disregarded unless specified.

Not sure If the pic below will be visible to you (I don't know how to properly copy a table from Excel and keep the formatting when pasting to this site).
