In Zoho Desk we have a field whereby we select an agent to a ticket, when I automate the extraction of the information into Excel the agent name is shown as a long number. I want to run a custom function in Zoho Flow that converts this number into a string before posting it into Excel.

This is what I have so far and it doesn't give me any errors but it also doesn't do what I want:

string ConvertTicket Owner(string ticketOwner)
{
owner_value = (ticketOwner.id).toString();
return owner_value.toString();
}

Any help on this is appreciated.
