How To Export Data from Classic ASP to CSV
Get deep insights into your CSV data with Sourcetable AI. Create custom charts, formulas, and reports. No Excel skills required.
Introduction
Exporting data from Classic ASP to CSV can be an efficient way to manage data for various applications. In this guide, we'll cover the steps necessary to perform this task seamlessly.
Proper data export ensures that information can be easily manipulated and analyzed in other software. By following our detailed instructions, you can simplify your Classic ASP data management process.
We'll also explore how Sourcetable lets you analyze your exported data with AI in a simple to use spreadsheet.
Exporting Data to CSV in Classic ASP
- To export data to CSV using Classic ASP, you first need to fetch the data from your Oracle database. This can be achieved using ADO with OLEDB, ensuring that your query retrieves the desired records into a recordset.
- For proper CSV export, set the Response.ContentType to "text/csv". Additionally, use the Response.AddHeader method to add a Content-Disposition header. This header should specify "attachment; filename=Export.csv" to prompt the browser to download the file with the specified name.
- Enable Response.Buffer by setting Response.Buffer = true. This improves performance by sending the complete response in one go instead of in chunks.
- To write data to the CSV file, use the Response.Write method. If you have a recordset, you can generate the CSV data using a loop or utilize the GetString() function to create the CSV in a single line. Make sure to use a comma as a delimiter and include quotes around fields if necessary.
- After writing the CSV data, use Response.Flush to send the data to the client. This ensures the data is transmitted immediately and the user can download the file without delay.
- If the data export operation is expected to take a long time, consider increasing the script timeout using Server.ScriptTimeout. This prevents the server from terminating the script prematurely.
- By following these steps, you can effectively export data to CSV using Classic ASP, ensuring a smooth and efficient process for generating downloadable CSV files.

How to Export Your Data to CSV Format Using Classic ASP
Set the Content Type
To begin, set the correct content type for the CSV file. Use the following line of code: Response.ContentType = "text/csv". This ensures that the data is interpreted correctly by the browser.
Specify the Filename
Set the filename for your CSV file using the Response.AddHeader method. The following line sets the filename to "Export.csv": Response.AddHeader "Content-Disposition", "attachment; filename=Export.csv".
Fetch Data from the Database
Use a Recordset to fetch data from an Oracle database (or any other supported database). Ensure your query retrieves the necessary data effectively.
Write Data to the CSV
Write the fetched data to the CSV file using the Response.Write method. You can append data line by line, using the vbNewLine constant to insert new lines.
Flush the Response Buffer
To manage large amounts of data and avoid timeouts, use the Response.Flush method. This sends the CSV data to the client in real-time and prevents the server from timing out.
Handle Script Timeouts
If generating the CSV takes a considerable amount of time, increase the script timeout using the Server.ScriptTimeout property. Set a higher value to allow ample time for the script to execute completely.
