Hello Davide,
Nothing is possibile with the rules? Regular expressions or something like that?
There is an option in CSVI multi replace rule with operation as Substring where you set the start(should be 0 to start at first character) and end of the character say 6 for the field you need only 7 characters to be read. Apply the rule on the template field and export. Check and let me know.
Kind regards,
Tharuna
