How to Sync Multiple PostgreSQL Tables with Excel Instantly Managing data between a robust database like PostgreSQL and a flexible spreadsheet tool like Microsoft Excel is a common workflow challenge. Manually exporting CSV files is slow, error-prone, and outdated. To maintain accurate reporting, financial modeling, or data analysis, you need a live, instantaneous sync.
Here is how to connect and sync multiple PostgreSQL tables with Excel instantly using the most efficient methods available today. Method 1: The Modern Way (Third-Party Add-Ins)
The fastest, most automated way to achieve instant, bi-directional, or automated one-way syncing is through specialized Excel add-ins like Coefficient, LiveFlow, or PowerSync. These tools remove the need for database drivers or complex scripts.
Install the Add-In: Open Excel, go to the Home tab, click Add-ins, and search for a data connector like Coefficient.
Connect to PostgreSQL: Open the add-in panel, select New Source, and choose PostgreSQL.
Enter Credentials: Input your database Host, Port, Database Name, Username, and Password.
Select Multiple Tables: Choose the specific tables or schemas you want to import. You can import them simultaneously into separate Excel sheets.
Set Instant Refresh: Toggle on the auto-refresh feature. You can set it to update every hour, daily, or trigger an instant refresh with a single click. Method 2: The Native Way (Excel Power Query)
Microsoft Excel has a built-in ETL (Extract, Transform, Load) tool called Power Query. It connects directly to PostgreSQL, though it requires a one-time driver installation. Step 1: Install the Npgsql Driver
Excel needs an open-source driver to communicate with PostgreSQL.
Download the latest Npgsql v3.x or v4.x installer (MSI file) from GitHub. Run the installer.
Crucial: During installation, ensure you select the dropdown option to install the driver into the GAC (Global Assembly Cache). Restart your computer. Step 2: Connect Excel to PostgreSQL Open Excel and navigate to the Data tab. Click Get Data > From Database > From PostgreSQL Database.
Enter your Server (IP address or localhost) and Database name. Click OK.
In the credentials window, select Database on the left menu. Enter your PostgreSQL Username and Password, then click Connect. Step 3: Select and Sync Multiple Tables
The Navigator window will appear, displaying all tables in your database.
Check the box for Select multiple items at the top of the window. Check the boxes next to all the tables you want to sync.
