Are your Excel tasks complex and time-consuming?


Excel, Essential for Office Work

ChatGPT×Excel: Functions & Macros Master Challenge

Meet us.


It will become a reliable assistant for your Excel work.




▣ Why did I apply ChatGPT to Excel work?

I teach Computer Specialist Level 1 at a vocational training institution and provide practical Excel training for institutional and corporate employees

Excel is something that students inevitably encounter when they obtain certifications and work at companies, or if they are practitioners at institutions and businesses

Most people only know the Excel functions they need for their work on a partial basis

As work becomes increasingly complex and voluminous, you'll find that your existing Excel knowledge alone isn't enough to meet your needs


How do you solve this situation?


Most people search the internet, look on YouTube, or students who learned from me sometimes contact me via email


However, this method doesn't immediately solve my problem


It takes time to search, and if I check my email late, it's usually already past the time when the issue needed to be resolved

I've always felt sorry about this part


What are some ways to provide immediate help when needed?


I usually make good use of ChatGPT. What if I apply this ChatGPT to Excel?

So when I explained the tasks I needed to ChatGPT and asked about the necessary Excel functions

ChatGPT provides surprisingly accurate answers and even kindly explains how to use them

Among the various Excel features, I found the use of functions and macro work (VBA code) particularly helpful

If you have concerns about Excel functions and macros, ChatGPT can be very helpful

What was created this way is [VOD] Excel Functions and Macros (VBA Code) Using ChatGPT.



This course is not just a lecture you listen to and finish, but is designed so that you can learn by following along with practical examples after listening to the lecture, and make it 'your own' by solving the given missions. And it is structured as a challenge course where you can fill in your weak areas with professional feedback from Teacher Eunhee



'ChatGPT×Excel: Functions & Macros Master Challenge'course consists of the following stages

  1. While taking online classes, I learned how to apply ChatGPT to functions and create macros

  2. I am submitting the mission on functions and macros

  3. You'll learn how to use functions and macros in ChatGPT while receiving professional feedback.


How to Complete the Mission

There is a mission prepared below the Basic Functions and Macros lecture
Read the mission description, download the mission attachment file, solve it according to the instructions, and submit it


Get professional feedback from Teacher Eunhee

When you receive feedback, you can discover shortcomings or habits that you might not notice on your own, and you can find solutions faster through others' opinions rather than struggling alone.
Additionally, positive feedback builds confidence, while advice on areas needing improvement provides motivation for growth.
In other words, you can feel a sense of achievement by reinforcing what you do well and improving what needs work.
Through Teacher Eunhee's thorough feedback on the missions you submit, you can fill in the gaps in your skills.

The photo below is feedback on the macro mission from the challenge missions



By the time the challenge course ends, functions and macros that once felt vague will

You will discover that it can be easily solved using ChatGPT

Now you'll be able to finish your work quickly



🎁 Course Benefits

  • You can ask questions anytime during the course → The instructor will answer directly

  • When you write a review, you'll receive the "Excel Tips PDF for Boosting Work Efficiency (100 pages)" e-book along with practice examples


▣ Then please tell me specifically in what cases ChatGPT can be helpful


1. If you've been searching the internet or asking colleagues about Excel functions or features you don't know well while working with Excel, now ask ChatGPT instead.


ChatGPT provides detailed instructions on how to do it, so you can just follow along.

For example, when you're unsure which function to use, you can ask ChatGPT a question that fits your work situation, and it will tell you the appropriate function to use. Then you can simply copy and paste the function it suggests.

Try solving various problems you encounter at work together with ChatGPT. This will reduce your work time and you'll have fewer occasions to feel sorry to colleagues or acquaintances because of Excel.


[Function Work Example]

Task situation: We need a function that calculates values based on multiple conditions.

ChatGPT Question:

"How do I write a formula that returns different results based on conditions?
For example, I want to sum the values in column J if the value in column B is 'Full Member', and sum the values in column K if it's 'Non-member'."


ChatGPT's response:



2. If you have repetitive tasks in Excel, ask ChatGPT to create VBA code for you.


Did you know that you can write VBA code in Excel?

When you need to perform simple but infinitely repetitive tasks on large amounts of data?

For example, if you need to insert flights in the middle of more than 1000 data entries, what should you do? Well..... you'll have to give up on leaving work on time.

In this case, VBA code is the answer. If you write and run VBA code, it will be done in less than a minute.
But what if I don't know VBA code....


Don't worry~~


We have ChatGPT

Even if I don't know VBA code, if I tell ChatGPT what task I want to accomplish, it will quickly create the VBA code for me.


[VBA Code Work Example]

Task Status: Need to change the background color to yellow for cells in column B where the value is greater than 100


ChatGPT Question:
Please create a VBA code that changes the background color to yellow for cells in column B where the value is greater than 100.


ChatGPT's response:



▣ So how can we use ChatGPT effectively?


You need to ask good questions (prompts).

ChatGPT and other generative AI systems produce different results depending on the question asked, which is why techniques for asking appropriate questions are necessary.

Wait a minute!!!

I don't really know how to ask questions?

Don't worry!!!

Teacher Eunhee shows you in the e-book how to ask questions about your Excel work to get the answers you want. By following the example questions in the e-book, you'll learn how to ask questions that will get you the answers you're looking for.


[Example Question]



▣ What do I need to prepare to use ChatGPT?

1. Please prepare Excel 2016 or a later version.

2. First, sign up for ChatGPT and log in. (ChatGPT 4o free version)

https://openai.com/index/chatgpt/

3. Among the attached files, download "Excel Example.ZIP" and extract it to an appropriate location.

Lesson 3: When creating macros for repetitive Excel tasks using VBA code, this explains how to have ChatGPT generate the code and then create and execute it as a macro button in Excel



▣ Frequently Asked Questions Q & A

Q. Can non-majors take this course?

Yes. Excel is a program widely used in all types of work, so regardless of your major, it will be useful for anyone to know.


Q. Why should I learn Excel functions?

Learning functions in Excel will enable you to use them in the right situations at work, increasing your work efficiency and allowing you to leave work on time.
In this video, you'll learn how to apply functions using ChatGPT, making it a bit easier and more convenient to implement functions.


Q. What is a macro?

When working with Excel, you'll encounter repetitive tasks. If you create a macro for these repetitive tasks, you can quickly solve them later by running the macro. The macro content is created as VBA code. We use ChatGPT to help with this VBA code.

    It was great to learn that I can easily utilize VBA, which I previously thought was difficult, through GPT. I hope there will be an advanced VBA course using GPT. I will definitely take it if such a course becomes available. Thank you.
