| | Numerical values by default are left aligned, however you can use the text alignment prefix characters to change this. Apostrophe(') left aligns. Double quotation marks (") right aligns. Caret (^) centre aligns and a Backslash (\) repeats the characters across the cell. | |
| | If you are using text alignment prefix characters to align text then the Caret and Double quotation will only work if you have the following selected (Tools > Options)(Transition tab, "Transition Navigation Keys"). | |
| | Every time you use a text alignment prefix character on a numerical value a small flag will appear in the upper left corner, indicating a potential problem. If this is intentional, just choose "Ignore Error" from the smart tag menu. | |
| | You can suppress the display of positive, negative or zero value by creating a custom number format in which the appropriate section is left blank. | |
| | You can format a number as text by prefixing it with an apostrophe (‘) or entering it as formula surrounded by double quotes. | |
| | If you want to avoid using pennies in your prices and your product is priced at $4.42, use the formula =CEILING(4.42,0.05) to round prices up to the nearest nickel. | |
| | Numbers in Microsoft Excel can never have more than 15 significant digits, but decimals can be as large as 127. | |
| | Any cells that are formatted as percentages are automatically multiplied by 100 so remember to enter them as decimals. | |
| | Sometimes when numbers are imported or copied into Excel they are sometimes converted to text | |
| | If a cell is displaying a formula as opposed to the value it could be that the cell is formatted as text. | |
| | If you enter a plus sign before a numerical value, then this plus sign is ignored. | |
| | If you enter a negative sign before a numerical value, then this is treated as a negative number. | |
| | If you see the letter "E" or "e" in a numerical value then this is to denote the exponent and represents "10 to the power" (i.e. 1E7 = 10,000,000). | |
| | If you use a forward slash in a numerical value but the entry is not a valid date then this will be interpreted as a fraction (e.g. 5 3/4 = 5.75) (e.g. 1/2 = January 2). | |
| | To display a number format that displays millions without showing the 6 zeros use the custom format "0,,". | |
| | To quickly remove all formats from a range of cells select (Ctrl + Shift + "~"). | |
| | To quickly reset the number formats for a selection, press (Ctrl + Shift + "~"). | |
| | To create a text entry that consists entirely of numbers, you can precede the entry with a text alignment prefix character, typically an apostrophe. (e.g. '123). | |
| | You can use a number format to change the colour of your cells. (e.g. "[Blue]$#,#0.00_);(£0.00)"). | |
| | If you enter a numerical value with a percentage sign then Excel will automatically apply the percentage number format "0.0%". This is equivalent to dividing by 100. | |
| | Numbers that are entered in brackets are treated as negative numbers. | |
| | To make sure that your fractions are never interpreted as dates precede the fraction with a 0 followed by a space. Excel will use the Fraction number format. | |
