"This is not a structured storage file" issue

[nkeung]

Hi Spire,

I am using Spire.Doc 6.12.9.4045 and I am encountering an issue converting the attached document. I got an error "This is not a structured storage file" right after this line.

document.LoadFromStream(file.InputStream, Spire.Doc.FileFormat.Doc);

Thanks,
Kevin

Hello,

Thank you for contacting.
After parsing your document, I found the format of it is docx but not doc, thus you encountered the error after specifying the FileFormat.Doc. When using LoadFromStream method, I suggest you use FileFormat.Auto to get rid of this issue. If there is any question, welcome to write back.

Sincerely,
Lisa
