🎯 Unique IDs are essential for combining data for reports, visuals and analysis. But what if your data doesn't have a unique ID….no problem just create an automated one using the techniques in this tutorial.

In this Microsoft Excel tutorial, I show you how to generate unique IDs for your data automatically without needing to rely on Power Query or the hassle of manual refreshing. You’ll learn how to create dynamic, self-populating IDs using a series of Excel functions that will save you time and effort when managing large datasets. By the end of this video, you'll have a clear understanding of how to generate unique IDs that stay consistent even as your data grows or changes.

Here’s a breakdown of the key topics covered in the tutorial:

📝 Creating Duplicate Check for IDs
Learn how to set up a duplicate check using the COUNTIF function to monitor the uniqueness of the IDs you generate. This ensures that when you add new data, you can quickly see if the IDs you're generating are truly unique or if there are any duplicates that need to be addressed.

📅 Using the DATE Function to Start ID Generation
I demonstrate how to combine the DATE function with other data points to generate an initial ID. While this alone might not give you a completely unique ID, it’s a good starting point for building a more complex identifier.

🔤 Incorporating Customer Information to Enhance Uniqueness
You’ll see how to merge the first letter of a customer’s name with the date to create a more unique ID. I also show you how to convert the letter into a numeric code using the CODE function, which further refines your ID without adding unnecessary complexity.

🔢 Leveraging Text Functions for More Complex IDs
To improve the uniqueness of your IDs, I show how to use the LEN function to calculate the length of text fields and combine this with other fields (like product name or order value) to generate a more unique ID.

💰 Working with Numbers and Rounding for Better IDs
I explain how to use the ROUND function to simplify and standardize numeric data (like order values) before incorporating it into your ID generation process. This helps ensure your IDs are both unique and easy to manage.

🔄 Combining Multiple Functions for a Robust ID
The tutorial walks you through how to combine all the functions into one formula that generates a unique ID for each row of data. I also explain how to adjust the length of the ID to meet your specific needs, ensuring that no duplicates remain as you work with larger datasets.

🔍 Ensuring True Uniqueness with Dynamic Updates
I show you how to test the final ID to make sure it generates correctly when new data is added. Using an efficient method, you can verify that each new ID remains unique without manually checking every entry.

✅ Streamlining Your Workflow with Built-In Duplicate Checks
To further optimize your process, I show how to set up a built-in duplicate check that automatically flags any duplicates in the ID column. This saves time and eliminates the need for extra columns, keeping your data clean and easy to work with.

By implementing these techniques, you’ll be able to generate automatic, self-populating unique IDs that update whenever new data is added, without the need for constant manual intervention. This will not only save you time but also help you manage and track your data more efficiently.

Learning these Excel functions is essential for anyone who works with large datasets and needs a scalable solution for generating unique identifiers. By mastering functions like COUNTIF, CODE, LEN, ROUND, and MID, you’ll improve your Excel workflow and ensure data integrity across your spreadsheets.

If you're tired of manually creating unique IDs or dealing with duplicate values in your Excel tables, this video provides the solutions you need. Follow along, and soon you’ll be generating unique IDs with ease and confidence.
