Adding a Calendar to a Worksheet
Using a specialized calendar control is a great way to let users add dates to a worksheet. Unfortuantely, Microsoft hasn't made it very simple to use such a control, as detailed in this tip.
Adding a Macro to the Quick Access Toolbar
The Quick Access Toolbar is a great place to put anything for which you want quick access. (Duh!) Here's how you can add your macros to the QAT so they can be run lickety-split.
Adding and Formatting a Shape via Macro
Excel makes it rather easy to add shapes to your worksheets. If you add a lot of shapes, you quickly discover that it can be a pain to do all the formatting to those shapes over and over again. This tip provides a way to insert a standard shape (an oval) and have it be formatted automatically.
Adding Buttons to Your Worksheet
You can easily add a button to your worksheet that will allow you to run various macros. This tip shows how easy it is.
Adding Dashes between Letters

Adding Leading Zeroes to ZIP Codes
Import a bunch of ZIP Codes into Excel, and you may be surprised that any leading zeroes disappear. Here's a handy little macro that can add them back.
Adjusting a Path Based on System and User
It is not uncommon to set variables in a macro based on other values, such as time or date. You could also set variables (such as a path on a drive) based on information such as a computer's name or the name of a user logged into a system. Here's how to determine those names (computer and user) so you can test the values in your macro.
Adjusting Values with Formulas
Paste Special is a great tool that allows you to modify the values in a range of cells in your worksheets. You may want, however, to instead change the values in cells into formulas that show how your modification was done. This tip examines how you can do this.
Appending to a Non-Excel Text File
Does your macro need to add information to the end of a text file? This is called appending, and is done using the technique presented in this tip.

Buttons Don't Stay Put
Excel allows you to easily add all sorts of objects and controls to your workbook. Sometimes, though, those items might behave in ways you don't expect. In fact, they might seem to move around and resize themselves without regard to your intent. Here's how to gain the upper hand in making those items behave as you expect.
Bypassing the BeforeClose Event
Hold down the Shift key as you open a workbook, and Excel bypasses any "startup macros" that may be in the workbook. If you want to bypass automatic macros triggered when closing the workbook, then you need to get a little more creative.
Calculating Only the Active Workbook

Changing Macro Cell References Based on Edits
Place a cell reference in a macro, modify the structure of your worksheet, and you may soon find that the cell reference in the macro is no longer accurate. While Excel doesn't automatically update cell reference in macros according to changes in a worksheet, you can avoid the problem by changing how you reference cells.
Changing the Default Drive
Do you have a macro that need to read and write files? If so, then there is a good chance you need to specify the default drive on which those files reside. Here's how to do it.

You can, from within your macros, easily display a message box containing a message of your choice. If you want to display that message box only when specific criteria are met, the challenge becomes a bit trickier.
Continuing Macro Lines
Sometimes a macro command line can get very, very long. This can make it hard to understand when you look at it a month or so from now. It is better to break your command lines up into individual lines that are easier to understand and document.

There is no intrinsic function that delivers this information to you, but you can develop a macro that should provide just what you are looking for.
Pausing Macros for User Input
Does your macro need to get some input from a user? Here are the ways that Excel provides for that input to be solicited.
