Transforming long data to a single column

Hi all, I have the following situation in which I attempt to transform long data (with multiple "genres" per unique title) to a single column, based on the unique title.

As an example, you can see #Redemption (2014) having 4 genres.

The problem in this case is that there are more than 10.000 different "genres", so I cannot first Pivot and then merge all the created columns due to limited column restaints.

Any trick to reshape this long data to a single "genre"  column without using the pivot option?

Doesn't matter if the delimiter is a space or a comma or something.

Kind regards,

Ferry
