3. Adding data (text only)

4. Saving with standard method Save

5. Exporting to Excel

6. Opening with Excel 2010

7. Do not work option "Format Cell" (Excel's window does not appear) and problems with backgrounds Area with data have white background - OK Areas outside the data range have an alternate color, which was previously specified only for the data area.
