For style reasons. You might want the text in the corner cell of a table to be at an angle for example. You might want titles for columns to vertically. It could be done to enable you to narrow the width of a cell. Often it is purely for effect, maybe to enhance a set of data and distinguish the titles a bit more.
You may do it for presentation or stylistic reasons. Sometimes you have a corner cell and might want text slanted in it for example. It is often for personal choice.
Yes. Go to Format Cells, but pressing Ctrl - 1. Then pick the Alignment and you can type in the amount of degrees that you want the text rotated. Alternatively text can be put into a text box instead of a cell and manually rotate it that way.
You cant rotate text
By default, text in Excel is left aligned.
Excel does not create stylized text, but you can insert WordArt. You will find the WordArt option in Excel 2007 on the Insert tab in the Text section.
In Excel it is between -90 deg and +90 deg.
A DOS editor is not capable of reading a standard Excel file. An Excel file must be opened with Excel or some application that can read Excel files. Text editors are not capable of doing that. They are designed for working on things like text files.If you have a standard Excel file and save it as a text file, then text editors can open them. All that will be in that is pure text, and not things like formulas and calculations and formatting etc. When you are saving as a text file, save it with a txt extension and most text editors will be able to open it. How you specifically do it will depend on the particular text editor you are using.
text in a cell
There is no reason why you cannot type that in. As there are letters in it, it will be treated by Excel as text.
The text will rotate 90 degrees to the right. The beginning of the text will be at the top. If you rotate another 90 degrees, the text will display upside down.
It is a spreadsheet, but not a text editor.
A lot of them are the same, but not all of them. For example, Ctrl - E does not centre text in Excel.
text means your writing, like a text box, you write in it! your welcome :)
