I think A1 and A2 aren't text, they are converted as numbers (right 
align in cell isn't it ?), but the column has text format.

When you change cell format, there is no conversion between text <-> 
number for already filled cells. But if you enter data in an empty cell 
(or replace existing datas), it will have the new format.

On the other hand, if you use de "Text to Columns" function, you can 
convert data type, but the cell format is left unchanged. So, further 
input in cells will have the cell format previously defined, not the 
data type used during the "Text to columns" conversion.
