Do you have access to Map or Pro? There are tools in both to sort/export domain tables, just can't use it to update the hosted data.
I do this with arcpy and the python API if you have access to them. Just need to get them into a sorted table with Code and Description. Then I use the following code to get it into the correct format:
def CreateDict(fieldname,domainname):
global update_dict
update_dict = {"fields": [
{
"name": fieldname,
"domain" :{"type" : "codedValue", "name" : domainname,
"codedValues" :[
{"name" : "Pathway", "code" : "Pathway"}
]}}]}
infc = BASE + os.sep + 'domaintable' # sorted table with domain Code and Desc.
with arcpy.da.SearchCursor(infc, ["Code","Street"]) as cursor:
for row in cursor:
update_dict['fields'][0]['domain']['codedValues'] += [{"name" : row[0] , "code" : row[1]}]
In this case, I am adding "Pathway" as I need it in my list, but is not in the table and will be at the top of the domain list.
this will format the update_dict to the proper format, then I use the API to get the layer and update it.
Example Output for the proper format:
update_dict = {"fields": [
{
"name": "Street",
"domain" :{"type" : "codedValue", "name" : "Streetnames",
"codedValues" :[
{"name" : "Pathway", "code" : "Pathway"},
{"name" : "89 PR SE", "code" : "89 PR SE"},
{"name" : "952 PR SE", "code" : "952 PR SE"},
{"name" : "974 PR SE", "code" : "974 PR SE"},
{"name" : "9th St", "code" : "9th St"},
{"name" : "Aaron Dr", "code" : "Aaron Dr"},
{"name" : "Abbot St", "code" : "Abbot St"},
{"name" : "Abert Ave", "code" : "Abert Ave"},
{"name" : "Acacia Ave", "code" : "Acacia Ave"},
{"name" : "Ada St", "code" : "Ada St"},
{"name" : "Adair Ct", "code" : "Adair Ct"},
{"name" : "Adair Dr", "code" : "Adair Dr"},
{"name" : "Adams St", "code" : "Adams St"},
{"name" : "Addison St", "code" : "Addison St"},
{"name" : "NA", "code" : "NA"}
]}}]}
lyr = my_agol.content.get('xxxxxxItemIDxxxxxxxxx').layers[0] # get the layer to update
update = lyr.manager.update_definition(update_dict)

PS, unless there is a need to have the code different that the description, would highly suggest you keep them the same (as in my example above, or @Katie_Clark's example) as you will have better results with fewer issues in the future. Domains don't all work the same in each client. sometimes it searches code, sometimes domain, sometimes displays one and not the other. The only way for it to be 'bulletproof' is if they are both the same.
