Split Operation:

Split the source column in two columns

The operation splits the source value in two values by "Char Sequence", "Index" or "Regex"

In the following examples the value is the string: "Fis-12345"
Split by Char Sequence:
Split on first occurrence of a specific character or sequence of characters

Ex. Split on char '-' separates the value as "Fis" and "-12345"

Ex. Split on char sequence "-s" separates the value as "Fi" and "s-12345"

Split by Index
Split the value at the specific position (the first index is 1). The position [n] corresponds to separate the value from [index 1] to [index n-1] and from [index n] to [index "end of value"]

Ex. Split on index 2 separates the value as "F" and "is-12345"

Ex. Split on index 5 separates the value as "Fis-" and "12345"

Split by Regex
Split by regular expression

Merge Operation:

Merge the source columns in a new column

The operation merges the two source values in a new value adding (eventually) a separator (a char sequence) between the source values

Ex. Merge values "Fis" and "12345" with separator "-" return the value "Fis-12345"
