You seem to be using it in the correct way, as per e.g. https://www.codetd.com/en/article/9255551 andExportAsFixedFormat().-
Check all your return results, e.g. from
QAxObject * document=documents->querySubObject("Open(QString)",QDir::currentPath()+ "/aaaa.doc");etc. -
Try some of the other examples in that thread, to see whether everything else works or whether it's only
ExportAsFixedFormat()which fails. -
Go try your call inside Word: write it in a VBA script there and/or try recording doing it manually and look at the generated code.

I think/hope the following is claimed to work from https://forum.qt.io/topic/128464/export-pdf-file-from-excel-template-with-qt-and-qaxobject/12workbook->dynamicCall("ExportAsFixedFormat(int,QString,int,int,int)",0,pdfFile,0,0,bIgnorePrintAreas);Note how that declares and passes the parameters. That is for an Ecel workbook, does that work same for a Word document?
UPDATE
Or for Word https://forum.qt.io/topic/127801/saving-from-word-to-pdf/2 claimsdocument->querySubObject("ExportAsFixedFormat(const QVariant&,const QVariant&,const QVariant&)", OutputFileName, ExportFormat, OpenAfterExport);does work, compare yours to that. That's all I know!

when i try check the return value of document->querySubObject("ExportAsFixedFormat(const QVariant&,const QVariant&,const QVariant&)",
OutputFileName,
ExportFormat,
OpenAfterExport);
I am getting QObject(0x0).for this
QVariant doc_op=document->dynamicCall("ExportAsFixedFormat(int,QString,int,int,int)",0,pdfFile,0,0,bIgnorePrintAreas);
I am getting QVariant(Invalid)can any one suggest , I am trying but it is not working please suggest if am missing some thing.

Please suggest if i need to add anything regarding this https://stackoverflow.com/questions/42909112/saving-word-document-as-pdf
in qt cpp , I dont understand how to include or how to proceed with this VBA script. -
@harsha123
You cannot use use the code in your last stackoverflow reference because it is VBA script and only for use from MS VB or within Word.I cannot see why your previous code should not work given that the thread I pointed you to says that it does.
I would give a go at the Excel print-to-PDF code from https://forum.qt.io/topic/128464/export-pdf-file-from-excel-template-with-qt-and-qaxobject/12 to see whether that does or does not work for you for Excel instead of Word.

This ExportAsFixedFormat() is also failing for excel conversion also when checked the return type getting Like QVariant(Invalid).

Looks OK, except no point keep adding the sameQT +=module repeatedly.https://docs.microsoft.com/en-us/office/vba/api/excel.workbook.exportasfixedformat says:
An error occurs if the PDF add-in is not currently installed.
I don't know that would cause your error message, but have you at least verified you can do the export to PDF what way from within your Excel/Word? Can you pick a different value for your
ExportFormatto see whether non-PDF works? I think Word has aSaveAsmethod for PDF instead ofExport, look up examples, does it work that way?You will have to figure how yourself, but if you take a VBA script example instead I think you can put it into a Word VBA script/macro inside Word and test running it from there. That needs to work....
