Doing it this way ensures all your parentheses are in the correct places.

Debugging Formulas
To troubleshoot complex formulas select the cell containing it and then click the = (Equal sign) to the left of the formula bar, this will activate the "Paste Function". To step through your formula simply click in the part of the formula you want to debug.

Highlight column A, then push Ctrl+G and click Special then check the Blanks option and click OK. Now push Equals (=) then the Up arrow and finally holding down the Ctrl key push Enter.

Click the collapse dialog box to the right of the "Import list from cells" box, highlight your range, click the expand dialog and then click "Import". Or type your entries in the "list Entries" box.

Adding Text to Formulas
To show a formula result and text or number(s) in the same cell type a & (Ampersand) after the formula then your text/number(s).

Adding Hidden Text to Formulas
Imagine you have a formula like: =$2018+$1056-4*$120. When you initially wrote it you knew what each number represented, but you come back later and can't remember. Add a hidden note to your formula by using the N() formula i.e. =$2018+$1056-4*$120+N("My Wage+Bonus-4 weekly loan repayments"). The N() function will convert text to zero.

Custom Format
You can format a cell to show any number or text without changing it's real value using "Custom Format". To see this type the number 20 in any cell then go to Format>Cells or push Ctrl+1. Select the "Number" tab and then select "Custom." Using any one of the pre-defined formats type "Twenty" (without quotations) or any text and then click "OK". To test it use the cell in any formula.

No More Chart Gaps
If you have a chart that is plotting empty text ("") or 0 (zero) from a formula then instead of using "" or 0 if the formula is False try using "#N/A" (without the quotations) or the formula =NA(). Or you can hide the Row(s) or Column(s). Either way Excel won't plot #N/A or hidden Rows or Columns.

My List
If you have a long list of Text with no blank cells between and you want to see a preview of what is in your list. Click in any cell within your list then right click and select "Pick from list", If you select one of the entries, Excel will insert it in the cell for you.

Remove Blank Rows
Highlight your range and go to Edit>Go to>Special and select "Blanks" then "Ok" now go to Edit>Delete or Ctrl+Shift+= (equal) and then select "Entire row" from the "Delete" dialog and click "Ok".

Sort Out Blank Rows
The quickest way to remove all blank rows is to select you range then go to Data>Sort.

See Formula cells
If you have a sheet full of formulas and you want to identify these cells at a glance go to Edit>Go to>Special and select "Formulas" then click "OK". Now go to Format>Cells or Ctrl+1 and select the "Patterns" tab and choose a color.

En Masse Changes
To make changes to more than one worksheet at the same time select one of the sheets, hold down your Ctrl key and click on each sheet name tab. Now any data entered one sheet will also be entered on the other(s). When you have finished right click on any of the sheet name tabs and select "Ungroup sheets".

En Masse Changes 2
Another way to have changes on one worksheet reflected on other sheets is to make all the changes you want on one sheet then hold down your Ctrl key and select the other sheet tabs. Go to Edit>Fill>Across Worksheets and Excel will give you 3 choices of what to copy to the other sheets i.e. "All", "Contents" or "Formats".

Worksheet Copy
Select the sheet name tab then hold down your Ctrl key and simply drag it to the position you want it.

Paste Reference
An easy way to reference another cell is to select the cell you wish to reference then right click and select Copy or Ctrl+C then select the cell you want the reference in, right click again and select "Paste Special" then click "Paste Link"

Absolute/Relative Toggle
If you have a formula you want to make absolute or relative then double click in the cell or F2 then place the insertion point anywhere in the cell address and push F4 1, 2 or 3 times.

Repeat
To repeat an operation push F4

Undo
To undo an operation push Ctrl+Z

Linked Picture
A good alternative to a textbox or any shape is a linked picture that reflects any changes made to its reference. To make one, select your cell(s) and holding down your Shift key go to Edit<Copy Picture. Make your choice from the "Copy Picture" dialog, then click where you want the linked picture and hold your Shift key down again and go to Edit and click "Paste Picture"

Run a Macro by Clicking a Cell
This is possible with use of VBA but let's face it most people don't know VBA so here is an easy way. Select the cell you want to run the macro and hold down your Shift key and go to Edit>Copy Picture then select "As shown on screen" from the "Copy Picture" dialog then hold down your Shift key again and go Edit and click "Paste Picture". Now right click on the cell picture and "Assign Macro".

Non Formula Result
Sometimes you just want the result from the Sum, Average, Min, Max etc from a group of cells without typing a formula in a cell. Excel allows you to do this very easily, first highlight the cells you want to evaluate then right click on the "Status Bar" and select the function you want and your result will be displayed in the "Status Bar".

Reduce File Size
When you have a workbook that is very large in size you can reduce this dramatically by saving the file as "Microsoft Excel Workbook (*.xls)" as apposed to "Microsoft Excel 5/95 Workbook (*.xls)". In other words avoid saving as multiple versions whenever possible.

Cell Navigation
To move through a group of cells that you are working with without going outside the range highlight the group of cells and then use the "Enter" key to move through them.

Quick Formula Syntax
When writing formulas for Excel sometimes you just need a quick reminder of the formula syntax. In this is the case then type an equal sign followed by the function name and push Ctrl+Shift+A. For Example typing =Vlookup and then pushing Ctrl+Shift+A will give you: =vlookup(lookup_value,table_array,col_index_num,range_lookup). The non-bolded arguments are optional.

Formula Errors
Whenever typing one of Excels functions (especially nested ones) into a cell always use lower case. This way when you push Enter Excel will capitalize only the names of the functions you have entered correctly.

Entering Named Ranges Into Formulas
When you write a formula, sometimes you want to use a Named Range as one of the arguments for the formula, but you cannot remember the name. In these times simply push F3 when you reach the argument that you want the Named Range in and Excel will display the Paste Name dialog. Click the name you want then OK.

Optional Function Arguments
Sometimes you may not be sure what arguments in a function are optional and which are not. If your using the Paste Function (Function Wizard) then the non-bolded arguments are optional.
