Question

I am generating reports resulting in WORD files using xdocreport.

From the generated report, I create a InputStreamContent with MIME-TYPE "application/vnd.openxmlformats-officedocument.wordprocessingml.document" (MS WORD – DOCX) to write to Google Drive :

// create Word file stream using xdocreport
OutputStream2InputStream outputStream = new OutputStream2InputStream(); // buffer
report.process(context, outputStream);
// create inputstream for Google Drive
InputStreamContent inputStream = new InputStreamContent("application/vnd.openxmlformats-officedocument.wordprocessingml.document",
        outputStream.getInputStream());
inputStream.setLength(outputStream.size());

WRITING MSWORD DOCUMENT WORKS FINE (CONVERT= FALSE) :

File file = new File();
Insert insertOperation = service.files().insert(file, inputStream).setConvert(false);
file.setTitle("test.docx");
file.setMimeType(inputstream.getType());
File result = insertOperation.execute();

Resulting in a WORD DOCX file created on my Google Drive.

WRITING SAME INPUTSTREAM WITH CONVERT=TRUE FAILS

File file = new File();
Insert insertOperation = service.files().insert(file, inputStream).setConvert(true);
file.setTitle("test");
//file.setMimeType(inputstream.getType()); // what here ? 
File result = insertOperation.execute();

RESULT

1. When NOT setting the mime type : newly created File result has 0 bytes and MIME-type: application/vnd.google-apps.kix

2. When setting the mime type : MIME-TYPE set to “application/vnd.google-apps.document” and convert = true, results in 400: BAD REQUEST.

What am I doing wrong ?

Answer 1

This is a common problem. Don’t set a MIME type in the request metadata. Google Drive will decide the MIME type to convert to.

Your line marked // what here ? should be left out.
