Export state and country picklists as CSV files from Salesforce by using the Chrome Developer Console to parse the XML in Address.settings

dumpCountriesAndStatesCsv.js

// Step 1, store the XML in a string
// Replace the string with the actual, full XML content copied as-is
// from Address.settings
var xml = '...';

// Step 2, parse the XML
// See https://www.w3schools.com/xml/xml_parser.asp
var parser = new DOMParser();
var xmlDoc = parser.parseFromString(xml, "text/xml");

// Step 3, traverse the xml
var addressSettings = xmlDoc.getElementsByTagName('AddressSettings')[0];

var countriesAndStates =
        addressSettings.getElementsByTagName('countriesAndStates')[0];

var countries = countriesAndStates.getElementsByTagName('countries');

// Initialize the list of state and country codes
var countryCsv = [['Country', 'CountryCode']];
var stateCsv = [['CountryCode', 'State', 'StateCode']];

var escape = function(value) {
    return '"' + value + '"';
};

for (var i = 0; i < countries.length; i++) {
    
    // Work on the current country
    var country = countries[i];
    var countryLabel = country.getElementsByTagName('label')[0].textContent;
    var countryCode = country.getElementsByTagName('isoCode')[0].textContent;

    // Add the country to the countries CSV
    countryCsv.push([escape(countryLabel), escape(countryCode)]);

    // Get the list of states for the country
    var states = country.getElementsByTagName('states');

    // Populate the states CSV
    for (var j = 0; j < states.length; j++) {
        
        // Work on the current state
        var state = states[j];
        var stateLabel = state.getElementsByTagName('label')[0].textContent;
        var stateCode = state.getElementsByTagName('isoCode')[0].textContent;

        // Add the state to the sates CSV
        stateCsv.push([
            escape(countryCode),
            escape(stateLabel),
            escape(stateCode)
        ]);
    }
}

// Step 4, print the CSV contents
var dumpCsv = function(csv) {
    csvLines = [];

    csv.forEach(function(row) {
        csvLines.push(row.join(','))
    })

    text = csvLines.join('\n');

    return text;
};

prompt('Select all, then copy', dumpCsv(countryCsv));
prompt('Select all, then copy', dumpCsv(stateCsv));
