Macro

What is a Macro?

A macro is an automated input sequence that imitates keystrokes or mouse actions. It is typically used to replace a repetitive series of inputs and used often in spreadsheets and word processing applications like Microsoft Excel and Microsoft Word.

The term macro is a shortened form of “macro-instruction” (long instruction). The file extension of a macro is commonly .MAC.

The concept of macros is also well-known among Massively Multiplayer Online Role-Playing Games (MMORPG) players and search engine optimization (SEO) specialists. In the world of programming, macros are programming scripts used by developers to re-use code.

By running a macro, users can trim down time that is normally consumed by repetitive tasks. Some macros, like the ones in Excel, may also contain functions.

How to Create Macros

There are different ways to create a macro depending on the platform. They are typically written in code or by using a macro recorder.

In Microsoft applications, you can write or record code using the Visual Basic for Applications (VBA) editor. To record a macro:

For instance, an Excel macro is typically created by recording a sequence of keyboard and mouse actions using the Macro Recorder. It can also be created using Visual Basic (because even a recorded macro is made up of Visual Basic code). A stored macro can then be accessed from a menu list or from the toolbar and run by simply clicking. You can also assign a hotkey to the macro for even faster access.

There are third-party macro software applications that also allow you to record the actions that you want a macro to automate, such as AutoHotkey, Macro Expres, and PhraseExpress.

You can create macros in programming as simple functions or scripts to automate repetitive coding tasks, while video-game macros are typically written using scripting tools or macro editors.

Once you have recorded a macro, you can assign it to a shortcut on your keyboard. Then, each time that you want to perform the function in the macro, you simply hit the key.

It is important to test a macro before you start using it to ensure it works correctly.

Macro vs. Function

Macros and functions both automate code, but there are important differences in how they work that have implications for their usage.

Functions tend to be preferred for structured and reusable code as they are more flexible and safer, whereas macros tend to be faster but have a greater risk of creating errors if not used carefully because they lack type checking.

Macros in Video Games

Macros have been widely popularized by MMORPGs since the introduction of Ultima Online in 1997. Originally, they were used to let the character perform repetitive actions to train certain in-game skills while the player was away from keyboard.

However, in recent years, macros have been used as keyboard or mouse shortcuts in other games. Instead of clicking several keys in a given order to activate an ability, a macro can be used to perform that action with a single button.

In some games such as Fortnite or other first-person shooter (FPS) games where time is of the essence, using macros is often regarded as a form of cheating, especially in competitive gaming. In fact, they could be exploited to infallibly perform actions that are otherwise too complex for a human to complete in a split second.

Among the different types of macros, batch macros are popular in games to create shortcuts for repetitive tasks, while GUI macros allow players to control in-game actions through graphical interfaces.

Macros in SEO

Macros are also used by SEO specialists to carry out repetitive tasks automatically and streamline processes. For example, macros can automate data scraping, report generation, and keyword research. They’re also used to format content that is regularly uploaded to a website, such as event dates, weekly reminders, and so forth.

SEO professionals can create macros to automatically update Excel spreadsheets and analyze large volumes of data or send out regular emails to partner websites for link placement and exchange purposes. A shared macro can be used across teams to facilitate collaboration and prevent duplicating efforts.

Macros in Computer Programming

In computer programming, macros are pieces of code that are given a name. They allow programmers to write code that is inserted into the program during compilation. Every time the name is used, the content of the macro is executed. This reduces the need to repeat code and can make the complete code more readable. Programming macros can resemble either objects or function calls.

5 Tips to Protect Yourself From Macro Security Risks

Macros are useful for streamlining processes, however, as macros can be called automatically as soon as a digital document is loaded, they have been employed by malicious individuals for creating macro viruses. What is a macro virus? Macro viruses infect documents that contain embedded macros and spread when a user opens the infected file and the virus runs its malicious code.

Here are five ways you can protect yourself from the security risks posed by macros:

Macros Pros and Cons

There are clear benefits to using macros but also some disadvantages to be aware of.

The Bottom Line

By definition, a macro, or “macro instruction”, is a series of instructions in code that when executed performs repetitive tasks automatically. Macros are used extensively in software suites such as Microsoft Office, as well as programming and gaming. They are powerful tools for streamlining processes and increasing productivity.

However, macros should be used carefully as they can pose a security threat or introduce errors. Regularly reviewing macros is key to ensuring they work as intended and protecting yourself from security risks.
