My upload is successful, but noticed after uploading file, it contains some additional comments as per below in the top of file, due to that, I am unable to process file .

Please advise.

    Hi @Ramakrishnan Venkatesan ,
    Per my test,I uploaded a file successful and correctly with following api: 

    _api/Web/GetFolderByServerRelativeUrl('/sites/abc/FolderTest/Test')/Files/add(url='rename.xlsx',overwrite=true)')

    We can set the file name after '/Files/add'. Since the error might caused setting filename by headers.
