Change data types of multiple columns at once?

[Anonymous]

Hello, I have a data set with around 50 columns and in the metadata, the columns are read as string where as i want it as a double. Is there any effective way where i can change them all at once instead of selecting each and every column and then individually changing their data type?

I think you misunderstood the question. Even with the help of this tool, i should get the dropdown of all my 50 columns. Is there an alternative of select all then change data types to double.
