JsonParser

The library perform operation on json and returns csv data in multiple output formats:

1. String
2. File
3. Writer

How you can use it:

To parse json input string to csv, you can do it by following ways:

Note: The following default separator "_" and delimiter "," are used while creating CSV.
Also there is an alternative to pass custom separator (e.g. "/") and delimiter(e.g. "|").

1. Output as String

   JsonParser.parse2Csv(INPUT_JSON_STRING); 
   // or
   JsonParser.parse2Csv(INPUT_JSON_STRING, CUSTOM_SEPARATOR, CUSTOM_DELIMITER);
   

2. Output as Writer

   JsonParser.parse2Csv(INPUT_JSON_STRING, WRITER_OBJECT); //e.g. StringWriter, FileWriter, etc.
   // or
   JsonParser.parse2Csv(INPUT_JSON_STRING, WRITER_OBJECT, CUSTOM_SEPARATOR, CUSTOM_DELIMITER);
   

3. Output as File

   JsonParser.parse2Csv(INPUT_JSON_STRING, CSV_FILE_PATH); // CSV_FILE_PATH e.g. test.csv or D://somefolder/test.csv or /home/user/downloads/test.csv
   // or
   JsonParser.parse2Csv(INPUT_JSON_STRING, CSV_FILE_PATH, CUSTOM_SEPARATOR, CUSTOM_DELIMITER);
