Java code sample (for reference)

[Example 1 ] Extraction Word text

Import com.spire.doc *. ;
 Import java.io.FileWriter;
 Import java.io.IOException; 

public  class ExtractText {
     public  static  void main (String [] args) throws IOException {
         // load test document 
        the Document DOC = new new the Document (); 
        doc.loadFromFile ( "Test.docx" ); 

        // Get saved text String 
        String text = doc.getText (); 

        // String to write the Txt 
        writeStringToTxt (text, "extracting text .txt" ); 
    } 
    public  static  void writeStringToTxt(String content, String txtFileName) throws IOException {

        FileWriter fWriter= new FileWriter(txtFileName,true);
        try {
            fWriter.write(content);
        }catch(IOException ex){
            ex.printStackTrace();
        }finally{
            try{
                fWriter.flush();
                fWriter.close();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
    }
