Use string.Length and string.Insert.

Hi
The expression be like this
If str_input = “15102019155246”
Then In assign activity
str_output = IF(str_input.Length<14,str_input.Insert(2,”anynumber”).ToString,str_input.ToString)

Where 2 is the index position and it starts from 0 for first character

Cheers @brunofl
