Autosum for Excel mobile
For the mobile application, it would be nice to have the autosum capability when I select a range of cells. Today I have to enter a formula in a cell.
Excel for Windows Mobile can save to PDF using the Print command. After tapping or clicking on the Print command you will see an option to print to PDF. This will save a PDF file.
In the desktop version, you can select a range of cells and it will show the average, count, and sum below the sheet automatically. I'm not sure what you mean by the sigma button in the mobile app, I don't see that. Could you explain in more detail?
