If you are using Java SE and can’t use foreign JARs, and your JSON is always simple as the example you posted, you can parse it. Here’s a short program that works for your example (but you will certainly have to adapt it if you have more complex JSON strings with more nesting levels and arrays):

public class SimpleJsonToXml {
    public static void main(String[] args) {
        String json = "{'sector':'Europe','organization':'Bazz Market Unit UK','companyCode':'UK1_2020','approvalManager':'03000069','managementLevel1':'X11','approvalLimit':'500000','access Category':'FTeam','currency':'USD','comments':'Need this access, so I can do my job properly'}";
        String jsonObject = json.replaceAll("\{(.*)\}", "$1");
        String[] childElements = jsonObject.split("(,)(?=(?:[^']|'[^']*')*$)");

        System.out.println("<root>");
        for (String item : childElements) {
            System.out.println(makeTag(item));
        }
        System.out.println("</root>");
    }

    public static String makeTag(String jsonProperty) {
        String[] element = jsonProperty.split("\:");
        String tagName = element[0].replaceAll("[' ]", "");
        String tagValue = element[1].replace("'", "");
        return "    <"+tagName+">"+tagValue+"</"+tagName+">";
    }
}

It will print:

<root>
    <sector>Europe</sector>
    <organization>Bazz Market Unit UK</organization>
    <companyCode>UK1_2020</companyCode>
    <approvalManager>03000069</approvalManager>
    <managementLevel1>X11</managementLevel1>
    <approvalLimit>500000</approvalLimit>
    <accessCategory>FTeam</accessCategory>
    <currency>USD</currency>
    <comments>Need this access, so I can do my job properly</comments>
</root>

To convert XML back to JSON you can use the native Java XML tools and parsers (org.w3c.dom and org.xml.sax, for example) and won’t need any external Jars.

If you are using at least Java EE 7, you can use the parsers in the javax.json package.
