|What Does it Do ?|
|This function calculates the value of a number, irrespective of whether it is positive or negative.|
|=ABS(CellAddress or Number)|
|The result will be shown as a number, no special formatting is needed.|
|The following table was used by a company testing a machine which cuts timber.|
|The machine needs to cut timber to an exact length.|
|Three pieces of timber were cut and then measured.|
|In calculating the difference between the Required Length and the Actual Length it does|
|not matter if the wood was cut too long or short, the measurement needs to be expressed as|
|an absolute value.|
|Table 1 shows the original calculations.|
|The Difference for Test 3 is shown as negative, which has a knock on effect|
|when the Error Percentage is calculated.|
|Whether the wood was too long or short, the percentage should still be expressed|
|as an absolute value.|
|Table 2 shows the same data but using the =ABS() function to correct the calculations.|
|You can calculate a persons age based on their birthday and todays date.|
|The calculation uses the DATEDIF() function.|
|The DATEDIF() is not documented in Excel 5, 7 or 97, but it is in 2000.|
|(Makes you wonder what else Microsoft forgot to tell us!)|
|Birth date :||17-Sep-81|
|Years lived :||36||=DATEDIF(C8,TODAY(),”y”)|
|and the months :||0||=DATEDIF(C8,TODAY(),”ym”)|
|and the days :||28||=DATEDIF(C8,TODAY(),”md”)|
|You can put this all together in one calculation, which creates a text version.|
|Age is 36 Years, 0 Months and 28 Days|
|=”Age is “&DATEDIF(C8,TODAY(),”y”)&” Years, “&DATEDIF(C8,TODAY(),”ym”)&” Months and “&DATEDIF(C8,TODAY(),”md”)&” Days”|
|Another way to calculate age|
|This method gives you an age which may potentially have decimal places representing the months.|
|If the age is 20.5, the .5 represents 6 months.|
|Birth date :||17-Sep-81|
|Age is :||36.08||=(TODAY()-C23)/365.25|

1. Use keyboard shortcuts
Following tricks help you to work smooth and fasting., shortcuts are the easiest way to speed up excel work.:
|CTRL + Arrow Keys||Quickly move around within your data. For example, CTRL + Down Arrow selects the last cell below the current cell that has data in it before it hits a blank cell.|
|F2||Begin editing the selected cell (just like double clicking the cell)|
|F4||Repeat the last action you took (e.g., applying formatting or deleting a row)|
|F12||The same as selecting Save As… from the File tab, but much quicker.|
|When Editing Formulas|
|F4||F4 will toggle the leading $ which makes the column and row parts of your references static (A1, $A$1, $A1, A$1)|
|F9||Also while editing formulas, pressing F9 will evaluate the selected part of your formula. This can be useful when error-checking your formulas.|
|TAB||Autocomplete the name of the function that matches what you’ve typed. For example, if you type “=CON” then press TAB, the formula will autocomplete to “=CONCATENATE(“.|
|Alt + Enter||Insert a line break into a cell without leaving formula editing mode.|
2. Conditional Formatting to view duplicate cells
Smart Tip: You can filter table columns by cell color. These two features together allow you to filter a table to show only duplicates.
3. Define Named Ranges
Named Ranges make it easier to refer to single cells or a range of cells in a formula by giving them a name. Simply select a cell or range of cells, click the “Name” box in the Formula tab and enter a name. Now, when you need to refer to the Named Range in a formula, just start typing its name and Excel will know which cell(s) you are referring to.
4. “New Window” on the “View” tab to look different sheets from the same file in separate windows
5. Create drop-down lists with Data Validation
It allow you to ensure that correct data is being entered into a spreadsheet, and can also alert you to incorrect data.
6. Quick Access Toolbar (QAT)
To add a feature to the QAT, right-click the item in the ribbon and click “Add to Quick Access Toolbar.”
Smart Tip: Add the “Paste Special” function to the QAT and you’ll be able to paste values or formats with two quick keystrokes (ALT + 1, then V).
7. Use INDEX–MATCH formulas
Smart Tip : Instead of VLOOKUP formulas with INDEX-MATCH
8. Employ Tables and Structured References
Tables and Structured References simplify formula writing. Similar to Named Ranges, columns of data will be named automatically by virtue of inclusion in a table. Not only does this keep your data clean and easy to understand, it’s a cinch to refer to data on other sheets, as well.
9. Use the Group feature to quickly show and hide columns or rows
Below example make you learn how to delete blank rows or rows that contain blank cells.
1. On the Home tab, in the Editing group, click Find & Select.
2. Click Go To Special.
3. Select Blanks and click OK.
Excel selects the blank cells.
4. On the Home tab, in the Cells group, click Delete.
5. Click Delete Sheet Rows.
