Output Data in SAS
SAS is a powerful programming language commonly used for data analysis and visualization. One important aspect of SAS is the ability to output data in various formats. Whether you need to export data to a different software system, create reports, or simply save a dataset for future reference, SAS provides several options for outputting your data.
Key Takeaways:
- SAS offers multiple ways to output data.
- Output formats include SAS data sets, text files, HTML, and more.
- Utilize PROC EXPORT, PROC PRINT, and ODS statements for different output requirements.
- Outputting data in SAS allows for easier sharing and analysis.
Data output in SAS can be accomplished using various procedures and methods. One commonly used approach is the PROC EXPORT procedure, which allows you to save a SAS dataset in a different file format such as Excel, CSV, or a text file. This is particularly useful when you need to share data with colleagues who may not have access to SAS.
Another useful procedure for outputting data in SAS is PROC PRINT. This procedure displays the contents of a SAS dataset in the SAS output window. It can be customized to include specific variables or observations, and even sort the data in a particular order. *You can apply formats and wanted variables to create custom output tables.*
Tables 1: PROC PRINT Example
| Variable Name | Data Type | Format |
|---|---|---|
| Age | Numeric | 8. |
| Name | Character | $20. |
| Gender | Character | $1. |
The Output Delivery System (ODS) is another powerful feature in SAS that allows you to generate output in various formats, such as HTML, PDF, Excel, and more. By using ODS statements, you can control the appearance of your output and incorporate formatting options such as titles, footnotes, and page breaks. *ODS provides flexibility in creating presentation-ready output with minimal effort.*
By default, SAS outputs the results of a procedure or data step to the SAS output window. However, you can also redirect the output to external files using various file referencing methods. This allows you to save your output for future reference or further analysis.
Tables 2: File Referencing Examples
| File Reference Method | Purpose |
|---|---|
| FILENAME statement with the DATALINES option | Redirects data directly within the SAS program |
| FILE statement with the appropriate file path | Directs the output to an external file |
Tables 3: ODS Statement Examples
| ODS Statement | Purpose |
|---|---|
| ODS HTML | Generates HTML output |
| ODS PDF | Generates PDF output |
| ODS EXCEL | Generates Excel output |
Outputting data in SAS provides several benefits. It allows you to easily share datasets with others, create reports for presentations or documentation, and save data for future analysis. By utilizing PROC EXPORT, PROC PRINT, and ODS statements, you can effectively output data in various formats, customized to your specific requirements.
So, the next time you need to output your data in SAS, remember the different methods and procedures available to you. Experiment with PROC EXPORT for file format conversions, PROC PRINT for displaying data, and ODS statements for generating formatted output. These tools will simplify your data output tasks and enhance your analytical capabilities in SAS.

Frequently Asked Questions
How can I output data in SAS?
There are several ways to output data in SAS, depending on your requirements. Some common methods include using PROC EXPORT, PROC PRINT, PROC REPORT, and the OUTPUT statement.
What is the purpose of PROC EXPORT in SAS?
PROC EXPORT is used to export SAS data sets to external files in various formats such as Excel, CSV, or HTML. It allows you to create a new file or update an existing file with the exported data.
How do I use PROC EXPORT to output data to an Excel file?
To output data to an Excel file using PROC EXPORT, you can specify the XLSX or XLS extension in the OUTFILE statement. For example, the following code exports the SAS data set “mydata” to an Excel file named “output.xlsx”:
PROC EXPORT DATA=mydata
OUTFILE='output.xlsx'
DBMS=xlsx;
RUN;What is the difference between PROC PRINT and PROC REPORT in SAS?
PROC PRINT is a basic data listing procedure that displays the contents of a SAS data set in a tabular format. On the other hand, PROC REPORT is a more advanced reporting procedure that provides greater control over the layout and style of the output, including options for summaries, computed columns, and conditional formatting.
Can I customize the appearance of PROC PRINT output in SAS?
Yes, you can customize the appearance of PROC PRINT output by modifying various options such as the WIDTH, NOCENTER, and STYLE parameters. Additionally, PROC TEMPLATE can be used to create customized output styles and formats.
How can I output data with specific conditions using the OUTPUT statement in SAS?
The OUTPUT statement allows you to create a new data set that contains only the observations that meet specific conditions. You can specify these conditions using an IF statement within the DATA step. For example:
DATA newdata;
SET olddata;
IF condition THEN OUTPUT;
RUN;What are the advantages of using PROC REPORT over PROC PRINT in SAS?
PROC REPORT provides more advanced features and options compared to PROC PRINT. It allows you to define complex multidimensional reports, including summaries, nested columns, and advanced formatting capabilities. PROC REPORT also offers more flexibility in terms of arranging and presenting data.
Can I output SAS data directly to a PDF file?
Yes, you can output SAS data directly to a PDF file using the ODS (Output Delivery System) functionality. By specifying the appropriate ODS destination, such as ODS PDF FILE=’output.pdf’, you can create a PDF file that contains the desired SAS output.
How can I output SAS data to a CSV file?
You can output SAS data to a CSV file using PROC EXPORT or the FILE statement within a DATA step. With PROC EXPORT, you can specify CSV as the DBMS option. If you prefer using the FILE statement, you can use the PUT statement to write the data in CSV format. For example:
DATA _NULL_;
SET mydata;
FILE 'output.csv' DLM=',' DSD;
PUT (_ALL_)(:);
RUN;What should I do if my SAS output file is too large?
If your SAS output file is too large, you may consider compressing it to reduce its size. You can use the COMPRESS= option with PROC EXPORT or utilize compression options in other output procedures like ODS PDF or ODS CSV. Another option is to split the output into multiple smaller files using techniques like splitting by observations or by variables.
