Project 1 Write macros to send automated invoice to debtors: The purpose of this course is to teach you how to use chat GBD and finish. Some of the complex tasks are automated, some of the repetitive and mundane tasks in Excel. So I'm not going to cover any of the basics of Excel to like what our rows and columns and what are the various tabs and exon. You can learn all of them in any basic Excel course or for free on YouTube. So let's straightaway, gets chartered with Excel macros and how Chad GBD can help to generate macros to automate your tasks. Our first project is automating an e-mail and wise to debtors. Let's say you have a list of people who owe money to your company. We call them guitars. In column j, we have their e-mail addresses, and in column B we have the amount they owe to us. Now we want to write a macro that send an e-mail to all these debtors telling them they owe so much money to us. If you know, macros, you know, you can do that easily. Now, let's see how Chad GBD can help here. Now to start with macros, I'll follow three simple steps. Step one, I'll save this Excel file as Excel macros file. For that, I need to save the file as x as m file. Normally Excel file extension is XLS. Now I need this file as XLS file, which is Excel macro file. It simple. Go to File, Save As and select Excel S M as the extension. Now step two, let's enable macros. I go to the ribbon up on top, right-click and click, customize the ribbon. On the right side. Let's check the developer checkbox. Click on Okay. Now let's go to Developer tab. On top-left, you'll find Visual Basic. Let's click on that. From your working Excel file. You can come to this page by simply pressing Alt F11. It's a toggle key. You can go back and forth between developer mode and worksheet mode using alt F 11. Step three, I'll go to insert and insert a new module. That's it. We've enabled macros in Excel. Now, I go to chat GPD to write a prompt. I copy paste the prompt from here. Just pause the video and read the prompt and understand it. Look at that. Chat GBD is generating Excel macro code for us. Here. It also tells us what we need to do so that this works well in Excel. Now I add another prompt that's good. In addition, include suitable text in the e-mail so that it should look as an official email center of a company that includes a suitable email text as well. Now, let's copy this code. Go to Excel and paste in within the module. I go to Tools and references. Here, I ensure that MS outlook object library is enabled. Now I've pasted in the code from Chad GPD. I'll just ensure that the columns are captured properly from Excel because that's where the base data is stored. I'll save this file again. Now I go to view the macros. We can see the macro we just created. Let me just run it. And boom, the e-mails are sent. We need to have Microsoft Outlook setup send such e-mails. As you can see, the males are in my sent items 6. Project 2 Write a macro to create Index sheet: Let's see more examples on how to write macros with Chad GBD. Now, let's say I have an Excel file with several sheets. In each sheet, I have a data store. Now, navigating between these sheets is a real challenge. If I want to have an index sheet with table of contents, in that it would make the job of navigating between these sheets much easier. Now, I want to create an index sheet with Table of Contents hyperlinked to the respective sheet. I need to write a macro program for this. Let's see how we can do this. With Chad GBD. I typed in this prompt in the chat GPT. Forget about all the previous instructions. Imagine that you're an expert in creating Excel Macros. Write a macro to create an index sheet in Excel. The index sheets should grab the names of other sheets in the file and create an hyperlinked text within the index sheet gives us suitable heading to the index sheet and list out all the names below with a hyperlink to the respective sheets. There you go. The macro code is ready. Now let's start implementing the macro using our regular steps. First of all, I'll save this file as Excel. Awesome. I'll call it as index dot XLSX. Now I copy the code from chat GPD and go to Developer tab. Visual Basic are simply I can use Alt F11 to toggle between the Excel worksheet and the visual basic coding sheet. I opened the module and paste in the code. And I save this file. Now let's go to run the macro view. Macros. There you go. The index sheet with hyperlinks is created 7. Project 3 – Macros to Creating random text: Many of us need Excel files with some random texts to work with. We can learn to work with many of the Excel functions and formulas. Only when we have Excel sheets that data. Manually creating data on an Excel sheet will take a lot of time and effort. How about automating it with macros? In this project, we'll create some random text in excel sheet using macros. As usual, I open a new Excel sheet and save it as XLS m-file. I give all f 11 to go to visual basic coding area within Developer tab. Now I open a module. Okay, Let's go to chat GBD now to give it a prompt. Forget about all the previous instructions. Imagine that you're an expert in creating Excel macros. Can you write an Excel macro, degenerate dummy text on a sheet from a to F B12. The first column should contain unique names, other people. The names should be people's names like ROM, reader, rank, get, angel, etc. Try not to repeat the same names. The next five columns should contain their marks scored in five subjects all and do digits. All of them can be random, but include column headers. Suitably. I must be able to generate this text in more than one sheet of an Excel file. Okay, We have the code ready. Let's copy this. Now, I go to VB module and paste in the code. I save it on effluent to go back to the Excel working sheet. Fa, to open the macros. Now I run the Macro that ego, the random text is ready. Let me open another sheet within this file. And I run macro on this sheet as well. Okay? When I run the code in the second sheet, macro is not responding to that. So let me go back to the chat GPT. I am not able to generate random text in the second sheet. Change the code so that I can generate random texts on more than one sheet within a file. Okay, Chat GBD has revised the code. Now, let me copy paste it into the Excel module. Let's see if this works. Yes, Now it works. Let me try on another sheet. Yes, it works fine. Now, this is how you should do when Chad GPD, make some mistakes. Clearly point out the mistake descriptively and ask what you want from Chad GBD 8. Project 4 – Macro for creating a Mortgage Calculator: At some point in time, we would have taken loans from the banks. It could be a whole loan or a car loan. For the loan, we pay monthly mortgage or equal monthly installments or EMI. How about creating a mortgage calculator? Our EMI calculator in Excel with chat GBD. Let's do that now. I create a new Excel sheet and name it as EMI calculator. I save the file with XLSX extension. Now alt F, the goto VB coding space. And open a new module. I go to Chegg GBD and give a prompt like this. Forget about all the previous instructions. Imagine that you're an expert and creating Excel Macros.

All of them may not work in the first try, keep giving your feedback to chat GBD and revise your prompts suitably 10. Project 6 Generate a formula with ChatGPT: In this project, I'll show you how we can generate a complex Excel formula with chat GBD. Let's say I have salesmen wise sales data in Excel. I want to calculate sales commission for the salesman. It is kind of complex because the commission has four slabs. Higher the sales they do hire the commission, they earn. Let's go to the chat GBD to generate salesman wise data because I don't have one to show as an example. So I'll generate the data table using chat GBD. Here you go with a prompt to generate the data table. First. Generate a data table to show the following. A two to 830 shows names of Salesman. Names are random. B2 to B3 shows sales numbers in INR. The numbers are between INR 10,000 to INR 100,000. Suitably provide column headings. Format the table in such a way I can copy paste it into Excel. So we have the data table ready. I'll copy pasted into Excel. Let me add a column. It shows sales commission. Now, I want to calculate sales commission for the sales numbers. Let me give a commission structure, recharge diabetes so that it can generate a formula, generate an Excel formula to calculate sales commission. If B2 is less than 100000 commission, if B2 is 10,001 to 20,005% commission if B2 is 20,001 to 40,010 per cent commission. If B2 is 40,001, 60,020 per cent commission. If B2 is more than 60,030% commission. So the formula is ready. I will copy paste it into Excel. You go, the commission is generated. I'll double-click here to copy the formula for all the rows. Now, let's make it even more complex. Randomly add a region for each salesman. I want chat GBD to check the region also before it calculates the commission. Here's the prompt. Generate an Excel formula for the following. If C1 is not our salt and b1 is less than 10,000, Commission is zero. B1 is 10,000, 20,000 commissioners, 5%. B1 is 20,000 to 40,000 commissioners, ten per cent, b1 is 40,001, 60,000, Commission is 20 per cent. If b1 is more than 60,000, Commission is 30%. If C1 is East are vest, and b1 is less than 10,000, Commission is zero. B1 is 10,001 to 20,000. Commission is ten per cent. B1 is 20,000, 140,000 Commission is 20 per cent, b1 is 40,001, 60,000 Commission is 30%. If b1 is more than 60,000, Commission is 40 per cent. As you can see, more commission is paid for salesmen from east and west compared to salesmen from not insult. Now, let's see how chat GBD generates the formula. So we got the formula. I'll copy paste it. It should be B2 instead of one. But anyway, let's copy this and the next row. There we go. We got the result. See it's a very complex formula. But Chad GBD made it easy for us. 11. Learn Functions and Formulas with ChatGPT: As you know, there are many functions and formulas in Excel. If you just know the name of those functions and want to know how to use those functions or formulas. You can use chat GBD learned the syntax of those functions and their explanation are already there in Excel, but Chad GBD can simplify the explanation to a great deal. Use this prompt to make any function easily understandable. Please explain this Excel function. Dash in simple words with examples, like you're teaching it to a ten year old kid. If required. Printer detailed data table first. Then show the example. If you're not happy with the examples asked for more simple or complex examples, chat GPD will oblige. In this template, you can replace the dash with any function you have in mind. Let's say we look up our index bar, match function, our average are some IF functions. If you don't know which function to use for which problem, then be descriptive on chat GBD so that it can tell you which one to use. How can I do that? First of all, I want to give the source data table format to check GBD. I would say I have my source data table in the format given below. And give a format like this. Now, if I want the Science and Math mark of a student to be printed in another sheet. Which formula or function to use. For this chat GPT gives the result. We don't want to read this full explanation. We just learned index bar match function can do this. Now, we'll go back to our template and use that to learn about Index Match function. In Excel, you can combine functions and formulas to solve complex problems. How can you do that? Just ask Chad GPT, how to combine two or more functions in Excel. Explain in simple words with examples. Like you're teaching it a ten year old kid. If required, print a detailed data table first, then show the example. As usual.

Learning Data Analysis using Pivot Tables and Pivot Charts: Pivot tables are a powerful tool to analyze complex data on an Excel sheet. Let's see how we can use chat GBD to learn to create a professional looking pivot table with all the bells and whistles, pivot charts and other advanced features to analyze the data. The first and foremost requirement to create a pivot table is data. Let's create that are using chat GBD. I give a prompt the chat GBD, to create a data table so that I can create a pivot table, create a data table, so that I can use it to create a pivot table. A2, A3, to contain ten different random salesman names like John, Philip, etc. B2 to B3 to contain four regions like north, south, et cetera. Again, random for all the salesman, C2 to C3, to contain different computer products like laptops, keyboards, mouse, Windows, software, etc. All of them random. D2, D3 to contain months like Jan, fab, etc. Again, they're all random due to eat 30 to have sales numbers 1000-100 thousand, depending upon the price of the products sold. You are suitable heading to the table columns. So we have a data table ready for use. If you want more data, you can ask for more in the same format. I mean, you can ask, give me 30 more rows of the same data. For the purpose of this video, let me proceed with the present era. Now, I copy paste this data into Excel. Now I asked Chad GPD to explain step-by-step to create a pivot table based on the above data. I want it to look professional and include all the advanced features of a pivot table. Chad GBD gives us various options to implement. First of all, let me insert a pivot table. I select the entire data. I go to Insert pivot table. Now I dragged the salesman in the rows region, also in the rows. I keep the products in the filter and months in the column. Now, the table looks like this. I can drag and drop them in different ways. The change the table format. I can see salesman wise table keeping the products in the filter are I can also see product wise table keeping the salesman in the filters. Or I can see a region wise table keeping the products and the column. Or I can choose the C month wise data. So I can move the fields as per my requirement. To make it easy for us to read and analyze the table, I want to add slicers. I go to each field and right-click and add that field as a slicer. Now with slicers, I can easily filter out what I don't want to see. If I want to see the performance of an individual salesman, I can do that. Or if I want to see the performance of a particular product, I can do that as well. Now, I choose the table and go to conditional formatting. And I can set a condition or a rule to see that on the chart. And I go to format table, but change the design. And when I click on the pivot table, I can see these two options. I go to Design and see options like subtotals, removed are added, granddaughters removed or added, or changed. The report layout. I go to PivotTable, Analyze, and add a pivot chart. Now, when I filter the table, the chart automatically changes. If you have any specific questions about pivot tables, ask Chad GBD and get the answers. That's data analysis using pivot table with Chad, GBD is help 13. ChatGPT for Data validation in Excel: Now I have salesmen wise sales data. Let's say I want to learn what is data validation in exon. So I asked Chad GBD like this, I copy paste the data set first and ask. Explain what is that I've added nation with the below data set. Show me an example and teach me as if you're teaching it to a ten year old kid. So they got the answer. Let's see what it says. Okay? Now, if I want to validate the user inputs in this column, I can do it. So if a user enters any other value apart from what I want, Excel will show an error. That's our validation. Now, let's implement it. Let's say I want to validate the region and month columns. Because regions cannot be other than these four regions. And months cannot be other than 12 months of the year. If a user makes any typo, Excel will show an error message.
