Uploading Data from Excel to SQL: Formatting Dates Correctly

When dealing with data management, especially in environments that involve Excel and SQL Server, formatting can become an issue. One common challenge that many users face is the need to correctly format dates when transferring data from Excel to SQL Server. If you find yourself in a situation where your date column from a CSV is in the mm/dd/yy format and you need to convert it to the SQL Server format of YYYY-MM-DD hh:mm:ss:000, this guide will walk you through the steps needed to achieve that using VBA.

Understanding the Problem

The default date format in your CSV might not align with the format SQL Server expects. This mismatch can lead to errors or even incorrect data being inserted into your database. As you continue working with Excel and SQL integration using VBA, it’s important to ensure that data types, especially dates, are consistently formatted.

Your Current Approach

You are currently using the following code snippet to get the date value from your Excel sheet:
