Problem:
When I attempted to import an MS Excel spreadsheet into MS Project, I was able to map each sheet to fields within MS Project; however, when I hit finished, I was getting an error “Operation Failed!” without any additional information.
Resolution:
After a quick Google, I found out that I needed to upgrade MS Project from SP2 to SP3. After successful installation, before you attempt to import another spreadsheet, be sure to open MS Project, go to “Tools” –> “Options” –> “Security” tab, and select the option to “Prompt when loading files with legacy or non default file format.” or “Allow loading files with legacy or non default file formats.”
