In a previous article, we explored how to import a CSV file into a table in MySQL. This is a continuation of that article, where we will explore how to split CSV files that contain data which is supposed to go into multiple tables.
Concerned that I had done something wrong, I Googled for a solution. Unfortunately, I didn’t find any answers there, so I ended up having to find the source of this warning myself.
Essentially, the CSV file format is meant to represent tabular data. The above CSV file represents the following table:

Due to their tabular nature, data in a CSV file can very easily be imported into and stored in an SQL table. The commands to do that, however, are not very well-documented online.
If a CSV file does not open as a text file on your computer, that’s because your computer is opening the file with a spreadsheet program such as Microsoft Excel. In such a case, to see the file as text, you will want to open these files on a text editing software such as Notepad.
