语法
public static java.lang.String toString(JSONArray ja) throws JSONException
In the below example, we can convert a JSON Array to CSV format.
Example
import java.io.File;
import org.apache.commons.io.FileUtils;
import org.json.*;
public class ConvertJsonToCSVTest {
public static void mAIn(String[] args) throws JSONException {
String jsonArrayString = "{\"fileName\": [{\"first name\": \"Ravi\",\"last name\": \"Chandra\",\"location\": \"Bangalore\"}]}";
JSONObject output;
try {
output = new JSONObject(jsonArrayString);
JSONArray docs = output.getJSONArray("fileName");
File file = new File("EmpDetails.csv");
String csv = CDL.toString(docs);
FileUtils.writeStringToFile(file, csv);
System.out.println("Data has been Sucessfully Writeen to "+ file);
System.out.println(csv);
}
catch(Exception e) {
e.printStackTrace();
}
}
}
输出
Data has been Sucessfully Writeen to EmpDetails.csv last name,first name,location Chandra,Ravi,Bangalore
以上就是如何在Java中将JSON数组转换为CSV
