In this Excel video tutorial, we gonna see how to use the Flash Fill tool or the Ctrl E Excel shortcut key.
Flash Fill automatically fills your data when it senses a pattern. For example, you can use Flash Fill to separate first and last names from a single column, or combine first and last names from two different columns.
Flash Fill in Excel is a powerful tool that helps automate data entry and formatting tasks. It recognizes patterns in your data and fills in the rest of the column based on the pattern you demonstrate. Flash Fill is especially useful for quick data-cleaning tasks, saving time and reducing errors when working with repetitive patterns.
How to Use Flash Fill
1. Enter an Example: Start by typing the desired result for the first row of data.
2. Activate Flash Fill:
Press Ctrl + E (Windows) or Command + E (Mac).
Alternatively, go to the Data tab and click Flash Fill in the ribbon.
3. Verify the Results: Excel will automatically fill in the rest of the column based on the pattern it detects. Review to ensure it’s correct.
Common Use Cases
1. Splitting Data: For example, separating first and last names from a full name column.
2. Combining Data: Merging first and last names into a single column.
3. Formatting Data: Reformatting phone numbers, dates, or other structured text.
4. Extracting Information: Pulling specific details from a text string, like extracting a domain from an email address.
Tips for Using Flash Fill
Consistency is Key: Ensure your examples follow a clear pattern; inconsistent examples can confuse the tool.
Manual Adjustments: Flash Fill might not always get it right on the first try. You can tweak the result, and Excel may learn from your corrections.
Enable/Disable Flash Fill: If Flash Fill isn't working, check if it’s enabled under File, Options, Advanced, Editing Options, Automatically Flash Fill.
Limitations
Static Results: Flash Fill doesn’t create formulas, so the filled data won’t update automatically if the source data changes.
Complex Patterns: For very complex transformations, you may need to use formulas or Power Query instead.
