Combine Many Columns To One

Essentially need a macro to combine the columns into 1 column.

Need a Macro to put everything in each "box" into one column, for example CU is the end of the first box, CV to GP is the second box ect. Essentially a box is the row where the yellow line is to the column where the yellow column is.

The problem is the setup of these colums change, sometimes they are bigger sometimes smaller and the spaces beneth it change. Sometimes I might have a column which goes to row 18 followed by 3 blank rows then the yellow box

I first design the first colum then select that and drag across to complete the rest ( my real file has links ect )

So I need a macro in which it can scan the first column up to the yellow line then put everthing within a "box " into 1 column, each )

then repeat the same process for other boxes with each box being put in its own column ( preferablly leaving an empty column in between )

THe file itself will help clarify any problem, if this request is not possible if it could combine every column into 1 column ( along with the spaces to the yellow line ) that would help also, i could manually cut each box into another column then.
