Excel & CSV Overview

Microsoft Excel is a spreadsheet application widely used for data organization, analysis, and visualization. It allows you to store data in rows and columns, perform calculations using formulas, and create charts and graphs for presenting information. 

While CSV stands for Comma-Separated Values, it is a plain text file format. Here, the data is stored in rows, with each value separated by a comma and each row terminated by a line break. It offers you a simple and universal way to exchange data between different applications.

Some uses of Excel and CSV include:

Data Storage: Both Excel and CSV can store data in a structured format, making it easy to organize and manage information.

Data Analysis: Excel allows you to do basic data analysis through its built-in formulas and functions. You can calculate average, sum, and perform more complex analyses with additional add-ins. CSV files are typically used for importing data into analytical tools for further processing.

Data Sharing: Both formats are widely supported by different applications, making it easy for you to share data between colleagues, partners, and other systems. CSV files are particularly suited for data exchange because they are lightweight and text-based.

Data Visualization: Excel provides various tools for creating charts and graphs, enabling you to visualize trends and patterns in their data. CSV files, on the other hand, require importing into specialized visualization tools for this purpose.

Oracle SQL Developer Export to Excel & CSV Methods

Extracting and transferring information from databases becomes vital when you work with data and is required for data analysis. This process is termed exporting; it serves as a bridge to enable data to be shared and analyzed effectively outside the database environment. Standard export formats like Excel and CSV provide user-friendly accessibility, facilitating in-depth analysis, reporting, and collaboration. 

There are various methods to export from Oracle SQL developer to Excel. Some are explained below:

Method 1: Export SQL Developer to Excel Using Export Wizard 

The Export Wizard in Oracle SQL Developer provides a comprehensive step-by-step approach to exporting data, offering more control and customization than direct methods:

Prerequisites:

• Oracle SQL Developer installed and configured.
• A database connection established within the SQL Developer.
• An SQL query to generate results you want to export.

Step 1: Login and Connect

• Open your SQL Developer and log in to your database using your credentials.
• Make sure you have a stable connection to the database you want to export from.

Step 2: Write Your Query

Write a query that retrieves the specific data you want to export. Here are some examples:

• Select all data from the customers table: SELECT * FROM customers.
• Get specific columns from the orders table for the year 2023: SELECT order_id, customer_id, order_date FROM orders WHERE order_date >= '01-JAN-2023' AND order_date <= '31-DEC-2023'.
• Hit the Execute button (or press F5) to run your query.

Step 3: Accessing the Wizard

• Right-click anywhere within the query results grid.
• Select Export... from the context menu.

• Alternatively, you can also go to Tools > Database Export > Start Wizard.
• The Export Wizard window will open up.

Step 4: Choosing the Source

In the Source tab, select the data to export:

• Format: Select Excel from the drop-down menu.‍
• Data Worksheet Name (optional): Enter a custom name for the exported data within the file (only applicable for "Table Data" and "Query Results").‍
• Query Worksheets Name (optional): Assign individual names to multiple exported query results within the file (only applicable for "Query Results").‍
• Saves as (compressed?): Select "Compressed Encoding" to save the file in a compressed format (e.g., .zip) to save space.‍
• Encoding: Choose the character encoding for the exported data (e.g., UTF-8) to ensure proper display of characters across different systems.‍
• File: Specify the destination folder and add file name for your exported data.

Step 5: Review and Export

• Go to the "Export Summary" tab to review the settings.
• Click "Next" if everything looks good.
• Click "Finish" to start the export process.

With this, you will have successfully exported data from SQL developer to your system in Excel format.

Method 2: PL/SQL Scripting to Export from Oracle SQL Developer to Excel

SQL Developer doesn't directly utilize PL/SQL scripts to export data. PL/SQL is a procedural language typically used within the Oracle database server for managing and manipulating data, not within the SQL Developer application.

However, you can utilize PL/SQL scripts alongside other tools or methods for exporting data from your Oracle database:

• DBMS_EXPORT: This built-in Oracle package allows you to export entire databases or specific objects (tables, views, etc.) using PL/SQL scripts. You need to run these scripts within the database server, not in Oracle SQL Developer. You can learn more about this method here: DBMS EXPORT
• UTL_FILE: This package provides functionalities for reading and writing text files within PL/SQL scripts. You can combine it with SQL queries to extract data and write it to a file for export.
• External Tools: You can use PL/SQL scripts to trigger external tools like SQL*Loader or Data Pump (expdp) for exporting data. These tools offer you more advanced features and options but require separate installation and configuration.
• Third-party libraries: Several open-source or commercial libraries like APEX_EXPORT provide functionalities for exporting data from Oracle databases using PL/SQL.

Both the Export Wizard and PL scripting offer ways to export data from SQL Developer, but each has limitations. The Wizard's simplicity restricts complex transformations and file formats, while PL scripting requires coding expertise and carries potential errors and security risks. Instead, you can opt out for a simpler and more straightforward option, Airbyte. This platform simplifies Oracle DB to Google Sheets transfers, eliminates scripting, empowers complex data manipulation, supports diverse file formats, and prioritizes data security.
