Hey Aris, your videos are really helpful and have helped me a lot. I have a question: after exporting the data to a CSV file, I want the exported data format to be XLSX instead of the comma-delimited format. I've been searching for a solution on RUclips and Chat GPT, but I couldn't find one. My guess is that you can probably figure this out using AppScript or a similar method. I hope you can help me with this.

It is possible to do this only by using the BOT, try this way.
