As a data analyst, you may have data in file formats like xlsx, csv, or txt. You are able to import these files into SQL for your use!
IMPORT CSV 'file_path' INTO table_name;
This will import all the columns from a csv file into a table. Then you can move forward with your analysis!

IMPORT TXT 'file_path' INTO table_name;
Same as with the csv, this will create a table with all the data from the file.
