Hi, that is a good tutorial. However, you have used a small number of excel files and have relatively similar column names. The real challenge is what if you have different column names, or rather inconsistent column names and the number of files is say 300? That is what you get in real-world data?

My problem is that I cannot read the excels from others directories... I have tried the /, \\, using the r before calling the directory. And Its impossible! Any suggestion?

Thank you for the video! I have a question about combining 3 xlsx files. If all 3 have different keys, for example sheet 1 and sheet 2 have the same key and sheet 2 has the same key as sheet 3. How do I use the appropriate left_on or right_on? And would I use how=left or inner?

Hi J, thank you for this awesome tutorial. I have 3 questions.

1. Let's say I have to do this every day. I have excel files named 2021_12_03Large, 2021_12_03Medium, 2021_12_03Small. How do I automate the r ' ' to adjust to the new date r'C:\Users\2021_12_04Large.xlsx', r'C:\Users\2021_12_04Medium.xlsx', without changing date/month every day?

2. How do you merge 5 files all at once, rather than 2 per time?

3. And the how = left, what if we want it to be 2 or 3 spaces to the left? instead of immediately to the left of a file? So column A, then next file starts at column D.

Thank you again. Hope you have a great week ahead!
