How to import CSV Files into SAS (With Examples)

---

You can use proc import to quickly import data from a CSV file into SAS.

This procedure uses the following basic syntax:

/*import data from CSV file called my_data.csv*/
proc import out=my_data
    datafile="/home/u13181/my_data.csv"
    dbms=csv
    replace;
    getnames=YES;
run;

Here’s what each line does:

• out: Name to give dataset once imported into SAS
• datafile: Location of CSV file to import
• dmbs: Format of file being imported
• replace: Replace the file if it already exists
• getnames: Use first row as variable names (Set to NO if first row does not contain variable names)

The following examples show how to use this function in practice.

Example 1: Import Data from CSV File into SAS

Suppose we have the following CSV file called my_data.csv:

We can use the following code to import this dataset into SAS and call it new_data:

/*import data from CSV file called my_data.csv*/
proc import out=new_data
    datafile="/home/u13181/my_data.csv"
    dbms=csv
    replace;
    getnames=YES;
run;

/*view dataset*/
proc print data=new_data;

The data shown in the SAS output matches the data shown in the CSV file.

Note: We used getnames=YES when importing the file since the first row of the CSV file contained variable names.

Example 2: Import Data from CSV File into SAS with No Header and Custom Delimiter

Suppose we have the following CSV file called data.csv:

Notice that this file has no header row and the values are separated by semi-colons instead of commas.

We can use the following code to import this dataset into SAS and call it new_data:

/*import data from CSV file called data.csv*/
proc import out=new_data
    datafile="/home/u13181/data.csv"
    dbms=csv
    replace;
    delimiter=";";
    getnames=NO;
run;

/*view dataset*/
proc print data=new_data;

The data shown in the SAS output matches the data shown in the CSV file.

By default, SAS provides the variable names as VAR1, VAR2, and VAR3.
