How Can I Run SQL Queries Directly on My Excel Data?

Running SQL Queries in Excel Sheets – Complete Guide

Introduction

Executing SQL queries in Excel provides powerful tools for data processing and analysis. However, many users are unaware of its native capabilities beyond simple table operations. This article explores various methods of running SQL queries directly in Excel.

Native SQL compatibility via external data connections

Excel provides a built-in data connection wizard that allows you to import data from external sources, including SQL databases such as Access or PostgreSQL. This method provides a direct connection to retrieve data as a dynamically linked table.

Microsoft JET and ACE OLEDB Provider

When setting up a connection through the Data Connection Wizard, specify the Microsoft.Jet.OLEDB or Microsoft.ACE.OLEDB provider. Access SQL (the underlying SQL dialect of Microsoft Access) is the native SQL for these providers.

Example query

In your context you can execute the query you mentioned as follows:

SELECT lastname, firstname, phonenumber
FROM [ExcelSheetName$]
WHERE phonenumber IS NOT NULL
ORDER BY lastname

Treat data as text

To ensure that the data is treated as text, append IMEX=1 to the extended attribute of the connection string. This prevents potential data corruption or operational issues.

Useful Resources

Here are some valuable resources for you to explore further:

• MSDN documentation on Excel data connection
• Support articles about Microsoft Jet 4
• Connection strings for Access and Excel
• Connect to Excel via ADODB using VBA

Note: When specifying a data source, the provider assumes that your data starts in a non-blank cell in the upper left corner. Avoid using worksheet titles above or to the left of the data.
