Convert PDF to Doc with Google Script Editor

Question

I'm looking to convert PDF to google Doc in Drive using Google Script Editor. However keep getting error message "Converting from application/pdf to application/doc is not supported". Is this conversion possible in script? My attempt as below, would be great to hear any advice.

function convertdPDF2doc() {
  var pdffile = DriveApp.getFileById();
  var pdfblob = pdffile.getAs('application/doc');

  pdfblob.setName(doc.getName() + ".doc");
  DriveApp.createFile(docblob);

}

Answer 1

function pdfToDoc() {  
  var fileBlob = DriveApp.getFileById('0B3m2D6239t6aWHo5TVpyYzhxV1U').getBlob();  
  var resource = {
    title: fileBlob.getName(),
    mimeType: fileBlob.getContentType()
  };
  var options = {
    ocr: true
  };
  var docFile = Drive.Files.insert(resource, fileBlob, options);  
  Logger.log(docFile.alternateLink);  
}

Add Drive API to google apps script project https://developers.google.com/apps-script/guides/services/advanced#enabling_advanced_services
