I use Excel much private and business. Of course I did not expect that the program has the same scope as the original. However, I had a little more expected. Simple inputs into a cell are possible. In formula to hack on the keyboard allerdiengs bloody fingers. Click cell references in a formula by are not possible. Formatting you can better look the same. Word is approximately equal to the editor that was delivered with my Samsung. Presentations I have not tried.
The program is suitable for viewing documents, however, only partially suitable for editing.
I already use Smart Office 2, which is better by a mile and have uninstalled this app again
