Additionally, we will explore how Sourcetable lets you analyze your exported data with AI in a simple to use spreadsheet.
Exporting Data to CSV Format Using Proc
- The PROC EXPORT procedure in SAS is a powerful and straightforward way to export data to a CSV file. This method is particularly useful for SAS users needing to transfer data into CSV format for analysis or sharing with others. The key options available in PROC EXPORT ensure that the process is flexible and customizable to meet specific needs.
- The basic syntax for using PROC EXPORT to export data to a CSV file is as follows:
- <code>proc export data=sas-dataset-name outfile='/path/to/output/filename.csv' dbms=csv replace; run;</code>
- This code specifies the dataset to export, the output file location, the file format, and the replace option.
- The <strong>data</strong> option (<code>data=sas-dataset-name</code>) specifies the SAS dataset to be exported. The <strong>outfile</strong> option (<code>outfile='/path/to/output/filename.csv'</code>) defines the location and name of the output CSV file. The <strong>dbms</strong> option (<code>dbms=csv</code>) specifies that the file type will be CSV, while the <strong>replace</strong> option allows overwriting an existing file with the same name.
- PROC EXPORT also includes additional options to enhance the export process. The <strong>delimiter</strong> and <strong>putnames</strong> arguments are used to customize the delimiter character in the CSV file and to control whether the header row is included. These options provide greater control over the output format.
- It is important to specify the correct file path in the <strong>outfile</strong> option. For example, <code>outfile='/home/user/data.csv'</code> ensures that the data is saved in the desired location. Incorrect file paths can lead to errors or the file being saved in unintended locations.
- Another method to define the output file is by using the <strong>filename</strong> statement. This statement creates a reference to the output file, which can be used in the PROC EXPORT step. This can streamline the code and make it more readable.
- Exporting data to CSV format using PROC EXPORT in SAS is efficient and versatile. By understanding and utilizing key options such as <strong>data</strong>, <strong>outfile</strong>, <strong>dbms</strong>, and <strong>replace</strong>, users can effectively manage and customize their data exports. Additional options like <strong>delimiter</strong> and <strong>putnames</strong> further enhance flexibility, ensuring that the output CSV files meet specific requirements.

How to Export Your Data to CSV Format Using Proc
Introduction to PROC EXPORT
PROC EXPORT is a powerful tool in SAS to export data to CSV format. This enables easy sharing and usage of data across various platforms and software.
Basic Syntax
The basic syntax for exporting data to a CSV file using PROC EXPORT is as follows:
proc export data=sas-dataset-name outfile='/path/to/output/filename.csv' dbms=csv replace; run;
Key Options
The data=sas-dataset-name option specifies the SAS dataset to export. The outfile option indicates where to save the CSV file. The dbms=csv option tells SAS to format the file as CSV. The replace option allows overwriting an existing file with the same name.
Using Delimiters
To change the default separator, use the DELIMITER= or DLM= statement. Enclose the delimiter in quotation marks. This is useful when you need a different separator than the default comma.
Including Headers
The PUTNAMES= option includes variable names in the first row of the CSV file by default. Set putnames=yes to include headers, or putnames=no to exclude them.
Handling Large Files
For exporting very large files, consider using a data step with the DSD option on the FILE statement. This approach can handle larger datasets more efficiently than PROC EXPORT.
Example Code
This example exports a dataset named my_data to a CSV file:
proc export data=my_data outfile='/home/u13181/my_data.csv' dbms=csv replace; run;
Conclusion
By following these steps, you can efficiently export your SAS datasets to CSV format using PROC EXPORT. Adjust the options as needed to fit your specific requirements.

Frequently Asked Questions
What procedure is used to export data from SAS to a CSV file?
The PROC EXPORT procedure is used to export data from SAS to a CSV file.
Which options need to be specified in PROC EXPORT to export a dataset to CSV?
You need to specify the input dataset using the DATA= argument, the output file using the OUTFILE= argument, and the file format using the DBMS= argument.
How can I include column headers when exporting data using PROC EXPORT?
Use the PUTNAMES=YES option to include column headers. This is the default behavior. To exclude column headers, set PUTNAMES=NO.
Can I filter the data I’m exporting to a CSV file using PROC EXPORT?
Yes, you can use the WHERE= option to filter the data when exporting it to a CSV file.
What happens if the output CSV file already exists when using PROC EXPORT?
If the file already exists, specifying the REPLACE argument in PROC EXPORT will overwrite the existing file.
