Can't open workbook on Web message due to external links: Have a visual in excel web for unsupported features
I would like to see excel web have either red text or a visual message indicating that a feature is blocked.
1. If a chart visual isn't supported than have a little grey square that says "Excel web don't support X kind of chart. Click here to view it in excel desktop"
2. if a certain cell query isn't supported than maybe have it highlighted with Red text.
