Connect to and Import External Data in Excel

Introduction

Bringing data from external systems into Microsoft Excel lets you create up‑to‑date reports, dashboards, and analyses without manual copy‑pasting. Whether the source is a SQL database, a web API, or a simple CSV file, Excel’s built‑in tools let you connect, import, and refresh data with a few clicks.

Why Connect to External Data?

• Eliminate repetitive copy‑and‑paste tasks.
• Reduce errors caused by manual data entry.
• Ensure every stakeholder works from the latest numbers.
• Enable automated refreshing for scheduled reporting.

Common Data Sources You Can Pull into Excel

SQL Server or Azure SQL Database

Use Microsoft Query or the newer Get & Transform (Power Query) to run SQL statements and import tables directly.

Web Services & OData Feeds

Connect to REST APIs or OData endpoints to pull JSON or XML data for sales, marketing, or inventory dashboards.

CSV, TXT, and Excel Files

Import flat‑file data using the From Text/CSV wizard. Set delimiters, data types, and preview the result before loading.

SharePoint Lists & Online Services

Excel can read SharePoint list data or connect to online services such as Dynamics 365 and Power BI datasets.

Step‑by‑Step: Creating a Data Connection

1. Open a new workbook and go to Data → Get Data.
2. Select the appropriate source (e.g., From Database → From SQL Server Database).
3. Enter the server name, database, and credentials. Test the connection.
4. Choose the tables or write a custom query.
5. Click Load or Load To… to place the data in a worksheet or data model.
6. Save the workbook in a trusted location (see below) so Excel can retain the connection settings.

Refreshing Data Automatically

• Press Ctrl + Alt + F5 to refresh all connections.
• Set a timer: Data → Queries & Connections → Properties → Refresh every X minutes.
• Enable Refresh on open for reports that must always show the latest numbers.

Trusted Locations & Security Settings

Excel will block external connections unless the file resides in a Trusted Location or you enable the “Enable Content” prompt. Add a folder to the trusted list via File → Options → Trust Center → Trust Center Settings → Trusted Locations.
