How To Separate Numbers and Letters in Excel Using the Flash Fill Feature
# How to Use Flash Fill in Excel to Separate Numbers from Letters: A Step-by-Step Guide
Welcome to our short course on using Flash Fill in Excel to separate numbers from letters and other data types within columns. If you're reading this, chances are you've come across a situation where your data is mixed—like the example provided: "gh4 n CDU 7869"—and you want to isolate specific parts of that data, such as extracting only the numbers or only the letters.
In a recent video, we demonstrated a formula-based approach to achieve this task, but it turns out there's an even simpler and more user-friendly method available in Excel: **Flash Fill**. Flash Fill has been around since Excel 2013 and is available in all subsequent versions, including the latest ones like Excel 2016 and beyond.
In this article, we'll walk you through how to use Flash Fill to separate numbers from letters (or any other data types) with ease.

## What Is Flash Fill?
Flash Fill is a powerful yet simple tool in Excel that allows you to extract or transform data within cells based on patterns it detects. It's particularly useful when dealing with mixed data—like the example "gh4 n CDU 7869"—where you want to separate numbers, letters, dates, or other types of information into different columns.
The key thing to remember about Flash Fill is that it relies on **patterns** to work effectively. If your data follows a consistent format, Flash Fill can quickly learn the pattern and apply it across your entire dataset.

## How to Use Flash Fill to Separate Numbers from Letters
Let's break down the process step by step using the example provided: "gh4 n CDU 7869." Our goal is to extract only the numbers ("4, 7, 8, 6, 9") into a new column.
### Step 1: Set Up Your Data
First, ensure your data is organized in a single column. For example:
| Original Data |
|---------------|
| gh4 n CDU 7869 |
| SDF 88889 |
| t2 FF |
### Step 2: Create an Adjacent Column for Flash Fill
Flash Fill requires you to manually enter the first few cells of the pattern you want. To do this, create a new column immediately next to your original data.
1. Click on the header of the new column (e.g., "B").
2. Type the desired output in the first cell. For our example:
- In cell B1, type `4` to indicate we want only the numbers.
### Step 3: Manually Enter Additional Data Points
Flash Fill works best when it has a few examples to learn from. Continue filling out the new column manually for the next few rows.
- In cell B2, type `8`.
- In cell B3, type `F` (garbage data, as shown in the transcription).
### Step 4: Use Flash Fill to Automate the Rest
Once you've entered your manual examples, it's time to let Flash Fill take over.
1. Select all the cells in your new column (from cell B1 to B3).
2. Go to the **Home** tab on the Excel ribbon.
3. Click on **Flash Fill** (located in the "Editing" section).
Excel will analyze the pattern you've created and apply it to the rest of the dataset. In our example, Flash Fill should correctly extract all the numbers from each cell in column A into column B.

## Troubleshooting Tips
If Flash Fill doesn't work as expected, there are a few things you can try:
1. **Double-Check Your Pattern**: Ensure your manually entered data clearly reflects the pattern you want Flash Fill to replicate.
2. **Force Flash Fill to Analyze**: If Flash Fill isn't picking up the pattern automatically, select the range of cells you want it to apply and click on **Flash Fill** again (still in the Home tab).

## Conclusion
Using Flash Fill is a quick and efficient way to separate numbers from letters or transform data in Excel. It's especially helpful for users who find formula-based methods too complex.
