DocConverter

DocConverter is a Java library to convert between XML, JSON, CSV and YAML documents. It's a utility class that can be called in a static way.

It takes a string as input in one data format and returns a string into another data format:

String json = DocConverter.convertXmlToJson(String xml) 
String yaml = DocConverter.convertXmlToYaml(String xml)
String csv = DocConverter.convertXmlToCsv(String xml)

String xml = DocConverter.convertJsonToXml(String json)
String yaml = DocConverter.convertJsonToYaml(String json)
String csv = DocConverter.convertJsonToCsv(String json)

String xml = DocConverter.convertYamlToXml(String yaml)
String json = DocConverter.convertYamlToJson(String yaml)
String csv = DocConverter.convertYamlToCsv(String yaml)

String xml = DocConverter.convertCsvToXml(String csv)
String json = DocConverter.convertCsvToJson(String csv)
String yaml = DocConverter.convertCsvToYaml(String csv)

If you have don't have a string as input you can convert several objects first to a string:

DocConverter.convertDocToString(Document doc)
DocConverter.convertNodeToString(Node node)
DocConverter.convertFileToString(String path)
DocConverter.convertListToString(List<String> list) 
DocConverter.convertStreamToString(InputStream inputsstream)
DocConverter.convertUrlToString(URL url)
DocConverter.convertUriToString(URI uri)	
 

For example changing a file from XML to JSON:
	
String xml = DocConverter.convertFileToString("C:/example.xml");
String json = DocConverter.convertXmlToJson(xml);
DocConverter.convertStringToFile("C:/example.json",json);

CSV

Conversion to csv expects input in the following flat format:

<rows>
	<row>
		<item1>x</item1>
		<item2>y</item2>
	</row>		
	<row>
		<item1>z</item1>
		<item2>b</item2>
	</row>		
</rows>
