How to make a blank cell have a dash?

Question

Google Sheets

Using the formula ARRAYFORMULA from a set of numbers (long code) 30091968369303, units are carried into different cells into one cell, all two into another, etc.
Those numbers that are not present in the long code would like to see a dash (-).
It looks more visual.

I would be grateful if there is a solution :)

Answer 1

Just add a condition to the formula

=ARRAYFORMULA(
  IF(
    REGEXREPLACE(Цифровое_представление; "[^"&Сетка_чисел&"]";"")="";"-";
    REGEXREPLACE(Цифровое_представление; "[^"&Сетка_чисел&"]";"")
  )
)
