Installing Npgsql for Excel Integration

Npgsql Installation Sources

To integrate PostgreSQL with Excel using Npgsql, the recommended source is nuget.org which provides the official releases. Daily builds from the continuous integration (CI) packages are also available, offering the latest updates.

Installation via NuGet

For the most stable experience, download Npgsql from nuget.org. Preview releases on nuget.org are generally safe and can be used for early access to features. To install, use the NuGet Package Manager in your development environment.

Continuous Integration Packages

For the latest builds, Npgsql publishes CI packages. There are two feeds: the patch feed for hotfixes, accessible at https://www.myget.org/F/npgsql/api/v3/index.json, and the vNext feed for upcoming versions, available at https://www.myget.org/F/npgsql-vnext/api/v3/index.json.

Global Assembly Cache Installation

Npgsql must be installed in the Global Assembly Cache (GAC) to be used with Excel. The Windows MSI installer, necessary for GAC installation, can be found on the Npgsql GitHub releases page for version 4.1.x. This method is unsupported for newer versions.

Configuring DbProviderFactory

After installation, register Npgsql's DbProviderFactory in the App.Config or Web.Config of your .NET Framework application. This enables the use of provider-independent ADO.NET types and prepares Excel for PostgreSQL connectivity.

Excel Integration Setup

Ensure Excel has a PostgreSQL entry in the 'Data - Get Data - From Database' menu to utilize Npgsql. Npgsql supports SSL, allowing secure connections between Excel and PostgreSQL servers.
