Honestly, I didn't understand it well when I first heard it ㅠㅠ (This is my first time using this kind of program ㅠ) After listening to it twice, I gradually understood it and applied it ㅎㅎ Since I can listen to it unlimitedly for 3 months? I'll keep listening whenever I have free time and make it mine ㅎㅎ There are times when I have to process a file in the same way every week and send it to a client or team leader. (In my case, it was an order list) When I have to do the same thing every week, I get a little dizzy. ㅎ I didn't come to the company for this ㅋㅋ But I used the knowledge I learned here to create a flow (Of course, creating a flow for the first time can take more time than editing Excel myself, but you only have to create it once), and whenever I need to, I just press Run and a new file comes out in no time. I can also automatically send emails to clients with this. ㅎㅎ It's so great. It saves time!! Please create more advanced lectures! ㅎㅎ
