You need to use the LOWER function and put the cell reference or text in the brackets:
=LOWER(A1)
=LOWER("I WANT THIS TO BE IN LOWER CASE")
Highlight what you want to change, press Shift+F3 to switch between "all small letter", "all caps" and "only first letter of words caps".
By default, text in Excel is left aligned.
In Excel you can use the UPPER function. You can put a cell reference into it or even specific text. =UPPER("change this") This will result in CHANGE THIS. =UPPER(A3) This will display the content of cell A3 in uppercase in the cell that the formula has been typed into.
An I-beam is a cursor on the mouse that makes it look like a capital "I". It happens when the mouse goes over highlightable text. When you mouseover text, the cursor changes its look, the new 'I' look is called an I-beam pointer.
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.
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
Ancient greek does not have small (or capital) letters
The PROPER function takes a piece of text and makes the first letter of each word a capital letter and all other letters as lower case. For example: =PROPER("This IS a piecE OF TeXT") The result of this would be: This Is A Piece Of Text
You cannot convert existing text from capital letters to small letters in Notepad. What you could do is copy the text and paste into a word processor and do it there. For example, if you pasted it into Microsoft Word, then select it and press Shift - F3 to convert it between the different cases. Then copy and paste it back to Notepad when you have it all in capital letters.
There is no reason why you cannot type that in. As there are letters in it, it will be treated by Excel as text.
It is a spreadsheet, but not a text editor.
