To Import or Not to Import • Usually preferable to have your data in (SAS7BDAT) format
– Stores SAS formats and metadata permanently– Rapid I/O (no translation required when querying data)
• REALITY CHECK– The #1 Business Intelligence tool in the world is…Microsoft EXCEL.– The #1 DBMS in the world is…Microsoft Access.– You will almost certainly be analyzing EXCEL/ACCESS data at some
point in your SAS career!
• When your source data changes frequently, you should consider linking directly to it in SAS– Otherwise you will be forced to constantly re-import into SAS datasets!– Eg. Real-time reporting on a production database (dashboards etc)
You can use Excel sheets/Access tables in SAS seamlessly as if they were SAS datasets by setting up a SAS libname that points to the spreadsheet / database!

Excel - How to do it1. Click on Libraries in the Explorer pane.
2. Right-click over any white space and select New to create a new library.
3. Under Name, type the libname you want to give your library (8 characters max!)
4. Under Engine, select EXCEL.
5. Under Workbook, click on Browse and select your Excel file.
6. Under Version, select the version of Excel workbook (usually 2002)
7. Under Header Row, select YES if the field names are on the first line of your Excel workbook (cells A1, B1, C1, etc).
8. Leave Options blank.
9. Check Enable at Startup if you want the library to be set up every time you load up SAS (otherwise you will have to repeat all of these steps every time!)
Access - How to do it1. Click on Libraries in the Explorer pane.
2. Right-click over any white space and select New to create a new library.
3. Under Name, type the libname you want to give your library (8 characters max!)
4. Under Engine, select ACCESS.
5. Under Database, click on Browse and select your Access database file.
6. Under DB Password, type the database password (if necessary)
7. Leave all other fields blank.
8. Check Enable at Startup if you want the library to be set up every time you load up SAS (otherwise you will have to repeat all of these steps every time!)
How to Use the Libnames in SAS
• Excel– Use the libname you
set up and the sheet name in the Excel file
– Excel spreadsheets by default contain three sheets: Sheet1, Sheet2, Sheet3.
• Access– Use the libname
you set up and then just use the table names as if they were SAS datasets!
Note the quotation marks, $, and the n.
