Introduction
Exporting data from Apex to a CSV file is a fundamental task for users looking to manage and analyze their data effectively. This guide will walk you through the steps needed to export your data from Apex with ease.
By converting your data to CSV, you ensure compatibility with various data analysis tools and software. We will also explore how Sourcetable lets you analyze your exported data with AI in a simple-to-use spreadsheet.
Exporting Data to CSV Format from Apex
- The APEX_DATA_EXPORT package is utilized to export data from Oracle APEX to various file types, including CSV. This package's EXPORT function returns data in the t_export type, which includes the contents in a LOB.
- Among the file types supported by APEX_DATA_EXPORT are PDF, XLSX, HTML, CSV, XML, and JSON. Exporting to CSV is a common choice due to its simplicity and compatibility with different systems.
- Oracle Application Express (APEX) should be upgraded to at least version 5.1.4 for exporting data. This version is the minimum supported for Oracle Database 18c XE. Older versions, such as 11.2 XE, require additional configurations like creating the DUMP_DIR directory object and granting appropriate privileges.
- To export data to CSV, start by querying the data you wish to export. The queried data should then be formatted as a CSV string. This data can be included within a Document file, and users can be redirected to download this file.
- Another method involves using the Salesforce Data Loader. Select an SObject, specify the location and name for the CSV file, and paste your query into the Data Loader. Visualforce pages can be used to create buttons that facilitate the download of the CSV file.
- Ensure the user has been granted the necessary READ and WRITE privileges if exporting from an 11.2 XE database. This also necessitates connecting to the database as user SYS with SYSDBA privileges to create the required directory object.
- After creating the CSV file, a common practice is to redirect users to download the file. This enhances user experience and streamlines the package flow within Oracle APEX.

How to Export Your Data to CSV Format Using Apex
Overview of Apex for Data Export
Apex is a powerful tool for data management and extraction, offering several built-in features for exporting data. One popular format for exporting data from Apex is CSV, which provides flexibility for sharing and analyzing data.
Using SOQL Queries to Shape Data
Apex supports complex SOQL queries, allowing users to precisely define the data they want to export. By customizing data selection, users can ensure that only relevant information is included in their CSV files.
Methods for Exporting Data to CSV
Apex offers multiple methods to export data to CSV. You can format queried data as a CSV string and leverage the Salesforce-provided Data Loader for exporting. For a more automated approach, you can use Apex's built-in tools to handle the export process programmatically.
Emailing CSV Files
One way to distribute exported CSV files is via email. Using the Messaging.EmailFileAttachment class, you can send the CSV file as an attachment. This is useful for sharing data with team members directly from Apex.
Creating and Storing CSV Files
To make CSV files available for download, you can use the Document object in Apex to store the files. This method allows users to download the CSV files whenever needed.
Using Visualforce Pages
Implementing a Visualforce page can greatly enhance usability. You can create a button on the page that, when clicked, generates the CSV file and presents it for download. This provides a user-friendly interface for data extraction.
Data Security
Exporting data in Apex adheres to strict data protection standards. Apex ensures that data exports are handled securely, reducing the risk of unauthorized access.
Steps for Exporting Data to CSV
To export data to CSV using Apex, follow these steps:
- Use the Salesforce Data Loader and select the SObject to export data from.
- Choose a location and filename for the CSV file.
- Copy/paste your SOQL query into the Data Loader.
- Use a Visualforce page to create a download button for the CSV file.
- Create a Document file to store and manage the CSV file.
- Redirect users to download the Document file.
- Use the Salesforce Data Loader and select the SObject to export data from.
- Choose a location and filename for the CSV file.
- Copy/paste your SOQL query into the Data Loader.
- Use a Visualforce page to create a download button for the CSV file.
- Create a Document file to store and manage the CSV file.
- Redirect users to download the Document file.
