There's a lot of external data that you can import into Excel and analyze. External data is data that is stored outside of Excel, in software accounting systems, mainframes, or databases, for example.
By importing the data, you don't have to type it into Excel.
Some of this data may be in text files, a common file format that Excel can read. For example, someone may want you to work with the data from one of the tables in their database, but they
can't grant you access to the database. So they convert the data into a text file,
and then you can easily import the data into Excel.
