There are a variety of methods to import Excel to PostgreSQL; some are simple, while others are more complicated, depending on the sort of data you receive and the format it is in.
In this article, you will discover four effective approaches for establishing a connection and seamlessly migrating your data from Excel to PostgreSQL. We’ll look at using ODBC drivers, integrating Excel and PostgreSQL via CSV files, and using a powerful tool like pgAdmin and using Microsoft Query to move data from Excel to PostgreSQL easily.
Methods to Connect Excel to PostgreSQL
There are many methods to import data from Excel to PostgreSQL. You will gain an understanding of four of them.
Hevo Data, a No-code Data Pipeline helps to load data from any data source such as Google Sheets, FTP, Google Search Console, SaaS applications, Cloud Storage, SDKs, and Streaming Services to a destination of your choice like PostgreSQL and simplifies the ETL process like Excel to PostgreSQL. It supports 150+ data sources (including 40+ free data sources) and is a 3-step process by just selecting the data source, providing valid credentials, and choosing the destination. Hevo not only loads the data onto the desired Data Warehouse/destination but also enriches the data and transforms it into an analysis-ready form without having to write a single line of code.

Method 1: Integrating Excel to PostgreSQL using ODBC Drivers
Get & Transform (Power Query) can be used to setup an Excel PostgreSQL connection using ODBC. This approach presupposes you’ve installed a PostgreSQL ODBC Driver.
Step 1: Install ODBC Drivers for PostgreSQL
The first step in Excel to PostgreSQL data transfer is to install ODBC Driver. The PostgreSQL ODBC 64-bit driver is available for download. On the machine where the Secure Agent is installed, install the PostgreSQL ODBC driver.
Step 2: Configure Postgres ODBC Driver in Excel
Expand the Get Data drop-down box after clicking Data in Excel. Select From Other Sources > From ODBC from the drop-down menu.

Step 3: Authorize Connection with PostgreSQL
Choose your data source name in the From ODBC dialogue (DSN). You can expand the Advanced Options dialogue box and input the connection string for your Data Source if you haven’t yet established your ODBC Driver (without credentials, which are defined in the credentials dialogue box in the next step). You can also enter a SQL query that will be performed immediately after connecting to the data source. Click the OK button.

Select Database and input your credentials in the dialog box, then click Connect if you’re using a database Username or Password. Select Default or Custom and press Connect if your database is not password-protected or if you’ve previously entered your credentials in the ODBC Data Source settings.

Step 4: Load Data in Microsoft Excel
Select the table from which you wish to retrieve data in the pop-up box and click on Load.

The table’s data will be displayed in an Excel spreadsheet, where you can interact with it further.

You have successfully completed Excel to PostgreSQL data transfer via ODBC Driver.

Method 2: Integrating Excel to PostgreSQL via CSV Files
Step 1: Excel File Conversion
The first step in the CSV method in Excel to PostgreSQL data transfer is to use Excel File Conversion. Open your file in Microsoft Excel if the file extension is xls or xlsx. This will need to be converted to a CSV file, which is a simple process. Simply Save As and modify the “Save as type:” to “CSV (*.csv)” before clicking Save. There is no need to change the file name to .csv because it will change automatically.
Step 2: CSV File Connection
Click Create and then Connection after right-clicking your Database Connection (or anyplace if your connections are empty). On the left, make sure the All tab is chosen, then scroll down to CSV. Now click Next.

Select the folder where you saved your CSV file from Microsoft Excel by clicking Browse. You’re choosing a folder rather than a file. All CSV files in that folder will be loaded by the connection. Finish by clicking the Finish button.
You should now notice a new connection, which is configured similarly to a standard connection. Each of the CSV files in your folder will be organized into a table with columns.
Step 3: Data Import
Data Import is the last step in the process of Excel to PostgreSQL data transfer. After you’ve established the Excel connect to PostgreSQL, you may query the data using SQL syntax, just like any other table. This data can now be imported into your PostgreSQL Table. Select Export Data from the context menu of the table you want to import into PostgreSQL.

Click Next after selecting Database. Change the target container to the schema in PostgreSQL where your table resides. Click on the OK button.

Choose the target (table) for the data to be imported. Set the target column for each data column by clicking Columns. This will map automatically if you have headers in your data that match the table columns. Click the OK button. Now, Next should be selected.
Image Source
Set the connection and Data Load options. Remove the option for truncating the target table if you only want to add data to the table rather than rewriting it. Now, Next should be selected.
After you’ve double-checked that the source and target are correct, click Start to begin the PostgreSQL Excel import.
The data from your PostgreSQL table is now available for selection.

You have completed Excel to PostgreSQL data transfer via CSV files.
Method 3: Transfer data from Excel to a PostgreSQL Database using pgAdmin
- Convert your Excel spreadsheet into a CSV file. To do this, click on file, then save as. In the drop-down bar that appears, pick CSV (Comma delimited), and then hit save.

- Create an empty table in PostgreSQL with the identical column names, data types, and column constraints as your Excel sheet’s columns.
Image Source
- In PostgreSQL, right-click on the newly formed table; a selection of choices will display; select the ‘import/export’ option.
Image Source
- At this stage, a dropdown menu displays. Here’s how to use the dropdown box:
- Choose the import option.
- On the file name tab, pick your excel sheet from your PC by clicking the select file (…) button.
- Choose ‘yes’ for the header choice.
- Choose the comma (,) delimiter as the delimiter choice.
- Click ‘OK’.

- If all rules are followed correctly, an import task is produced. A process observer appears to assist you in keeping track of what’s going on.

- You’ve successfully loaded the table into your relational database management system.

Method 4 : Move Data from PostgreSQL Database to Excel using Microsoft Query
Here’s a detailed guide on how to establish a connection between Microsoft Excel and a PostgreSQL database using Microsoft Query:
Step 1: Begin by opening the Excel sheet where you intend to import data from PostgreSQL. To do this, go to the “Data” tab, then select “Get Data,” followed by “From Other Sources,” and finally choose “From Microsoft Query.”

Step 2: In the next window, select the desired data source and make sure to enable the option that says, “Use the Query Wizard to create/edit queries.” Confirm your selection by clicking the “OK” button.
Step 3: Now, you’ll need to specify the database connection details. This includes providing the database name, username, and password. Once entered, click the “OK” button to proceed.
Step 4: In this step, you can select the specific tables you want to import into Excel. Additionally, you have the option to apply filters or sort data in rows and columns as needed. To add the selected tables, click the “Add” button.
With these steps completed, you will see that your PostgreSQL data has been successfully loaded into an Excel sheet.
Furthermore, you have the option to utilize other features in the “Get Data” tab, such as the Data Connection Wizard, Power Pivot, and Query Wizard, to export query results from your PostgreSQL database to Excel.
- Power Pivot: This Excel add-in empowers you to import data from external sources, including PostgreSQL databases. While importing, you can apply data filters or rename columns. After the import, Power Pivot efficiently organizes the tables on separate sheets in Excel. Moreover, you can utilize the Data Analysis Expression language within Power Pivot to create advanced formulas, allowing you to craft custom data models.
- Query Wizard: The Query Wizard serves as a valuable tool to create and modify queries for accessing your database’s stored data.
