You have to take each row and
I think these 4 steps should help:
Use zip
Explode
Withcolumn (getelement of array)
Drop the array column
Thanks

@Enrico Minack I used arrays_zip to merge values
into one row, and then used toJSON() to export the data.
@Bjørn explode_outer didn't yield the expected results.
Thanks anyway.

Use explode_outer() when rows have null values.

I am not expert, may be try if this works:
In order to achieve the desired output using the explode() method in
Java, you can create a User-Defined Function (UDF) that zips the lists
in each row and returns the resulting list. Here's an example
implementation:
typescript
Copy code
import org.apach
You have to take each row and zip the lists, each element of the result
becomes one new row.
So turn write a method that turns
Row(List("A","B","null"), List("C","D","null"), List("E","null","null"))
into
List(List("A","C","E"), List("B","D","null"), List("null","null","null"))
and use flatm
Hello guys,

*col3*
"A"
"C"
"E"
"B"
"D"

"null"
How to do that (preferably in Java) using
