🧭 Wondering How to Begin?
When I first explored how to clean data in Excel using Copilot, I didn’t know where to start. It wasn’t about technical skill—it was about learning to ask the right questions. And surprisingly, Copilot responded better to natural, everyday language than complex Excel jargon.
These steps are what helped me ease into it. If you’re just getting started or even if you’ve cleaned data before, these suggestions can smooth out your workflow using Copilot. Let’s walk through them together.
1. 🧾 Open Your Excel File
Start by launching your Excel file and making sure Copilot is enabled. It’s usually located in the ribbon if your Office version supports it. Make sure the data you want to clean is clearly marked—usually in table or structured column format.
2. 💬 Ask Natural Language Questions
You don’t need to know formulas. Just type a prompt like, “Remove all rows with missing values in column C”. Copilot understands what you mean and offers to apply the changes. This makes “how to clean data in Excel using Copilot” easier for anyone, not just data pros.
3. 🧹 Remove Duplicates
This is one of my favorite quick fixes. Just type something like, “Delete all duplicate rows based on column A”. Within seconds, Copilot filters and cleans your sheet.
4. 🧼 Standardize Date Formats
Dates can be tricky. I’ve often seen columns where the dates are mixed between U.S. and international formats. You can write, “Convert all dates to DD-MM-YYYY format”, and Copilot applies the change consistently across the file.
5. 🔠 Trim Extra Spaces and Capitalization
If your data has random spaces or inconsistent capitalization, ask Copilot: “Trim extra spaces and make all text in column B lowercase”. It’s a fast way to bring uniformity to your spreadsheet.
6. 🧮 Identify Outliers or Errors
You can ask Copilot to highlight or flag unusual numbers. I once had a revenue column where a few values were off by 10x. A prompt like “Highlight cells where values deviate significantly from average” made it easy to catch errors.
7. 🔗 Merge or Split Columns
Combining first and last names or splitting addresses becomes effortless. Prompt something like, “Merge column A and B with a space between” or “Split column C into city and zip code”. Copilot handles it precisely.
