Expanding/Duplicating Rows with the same values?
I want to be able to duplicate a row only if the value is 2, 3 or more - so that it will duplicate it to this value (ie 2 = 2 rows). The rest of the row includes workers details. Is this possible?

= Table.TransformColumns( from, { "Count", (x)=> List.Transform(List.Repeat( {x},x),(y)=> 1) } )
Yes, you can do it in power query For it

= Table.TransformColumns( from, { "Count", (x)=> List.Transform(List.Repeat( {x},x),(y)=> 1) } )to
= Table.TransformColumns( from, { "Count", (x)=> List.Repeat( {"1"},x) })

this can be done in power query
make a small example so we can help youI have created a pbix file but you can't upload that here, would an excel sheet be better?

Well done.

= Table.TransformColumns( from, { "Count", (x)=> List.Repeat( {"1"},x) })(Before)

How would the formula change for any additional columns such as the imaginary one I have added? The logic is if 0 then = 0 (I got Null), IF 1 = 1, Else IF greater than 1 (2 or more) than duplicate the entire row.
This is effectively what I want to do - (1st is before - 2nd screenshot is after) - Obviously just much more data.
