Too many columns when downloading subsets for excel

I am trying to download a subset data set of the CRISPR DEPmap data as .CSV. I tried to import into excel and the import has too many columns - the download has the all the genes as columns which overloads the limit of excel, with the cell lines as rows. Is there a way to change this in the download so that the download file can be opened in excel?

One can use the “custom download” tool to export a subset of genes, which would keep you under excel’s limit.

Or assuming you could load the data into excel? What would you want to do with it in excel? (I find that excel isn’t well suited for manipulating large amounts of data, so I wonder if there’s a different way to achieve your goal)
