Expanding/Duplicating Rows with the same values?

agd50_0-1679375048108.png 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?
(sensitive data)

 List.Transform(List.Repeat( {x},x),(y)=> 1)

I'm sorry, you can shorten the M code like this

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

to

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

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.

You are a champion, I wish i had your brain. I assume that this is M Code?

Well done.

This is effectively what I want to do - (1st is before - 2nd screenshot is after) - Obviously just much more data.

this can be done in power query
make a small example so we can help you

I have created a pbix file but you can't upload that here, would an excel sheet be better?
