Extract a column of data from a text file (part 2)

[45179902]

This question is similar to Solved: Extract the last two values from rows in text file... - Alteryx Community

A text file includes data like this:

ISP-123456    2    C    2   2

ASI-123213    A    3    1    5

PSI-123233    A    2    3    7

SRI-213232          1    4    9

SIR-122323    1    2   24   0

TIS-123980    C    B         1

BSI-231897    1    3     8   T

Suppose that I always want to extract the values from column 4 ( 2, 1, 3, 4, 24, 8 ) if there is a value in that column. How do I achieve this?

if regex_match([test],"^.*\s(\d+)(\s.*$)") then
regex_replace([test],"^.*\s(\d+)(\s.*$)","$1",0) else null() endif

works with your sample data - in a formula tool. This assumes that the second to last row should be a null and any entries that don't have a number in the fourth position should be nulls.
