We have created a web page in our corporate intranet for business users to submit project requests. Our developer uses the Clarizen API to create the project in Clarizen and upload any attachments. In Clarizen, when we access the submitted project and click on the attachments, we get error messages for both .docx and .xlsx. We don't get the messages if the attachments are .doc or .xls. Is there special coding that we need to do to better handle .docx and .xlsx?
For an.xlsx, the first message we get is 'we found a problem with some content in 'filename'. Do you want to try to recover as much as we can? We click on Yes. The second message is Excel was able to open the file by repairing or removing the unreadable content.
