Dirty data is every analyst’s nightmare: duplicates, extra spaces, inconsistent formats… But Excel can fix these issues in seconds! Discover 5 lifehacks that will save you hours of manual work. No VBA required – just clever functions and underused tools.
🎯 Why Clean Data?
- Errors in reports caused by incorrect numbers or text
- Wasted time on manual editing
- Automation roadblocks in workflows
Real-world example: Extra spaces in phone numbers caused a marketing campaign to reach only 30% of customers.
🔥 5 Data Cleaning Hacks Excel Pros Never Share
1. Text to Columns: Split Data Like a Pro
Problem: Combined data in one cell (e.g., “John Doe,New York,01/01/2023”).
Solution:
- Select column → Data → Text to Columns
- Choose “Delimited” → pick your separator (comma, space, etc.)
- Set formats for new columns
Pro Tip: For fixed-width splitting (e.g., “JohnNY2023”), use Fixed Width mode.
2. TRIM + MID: The Space-Killing Combo
Formula Magic:
=TRIM(MID(A2,SEARCH(" ",A2)+1,LEN(A2)))
What it does:
- Removes extra spaces (keeps single spaces between words)
- Extracts specific text (e.g., removes “ID:” prefixes)
Example:
Before: " John Doe "
After: "John Doe"

3. Conditional Duplicate Removal (No Built-in Tool)
Challenge: Keep only unique rows where Column A = “London”.
Solution:
- Add helper column with:
=COUNTIF($A$2:A2,A2)
- Filter values >1 → delete rows
How it works: Flags duplicates starting from first occurrence.
4. Power Query: The Ultimate Cleanup Machine
For complex tasks (merging tables + value replacements):
- Select data → Data → From Table/Range
- In Power Query:
- Remove blanks (Home → Remove Rows)
- Replace “N/A” with zeros (Replace Values)
- Standardize date formats (Data Type)
- Close & Load – done!
Bonus: Set it once → reuse with “Refresh” for new data.
5. Find/Replace with Wildcards (*)
Works for numbers too! To remove text after dots:
- Press Ctrl+H
- In “Find what”, enter:
.*
- Leave “Replace with” empty → Replace All
Before: "Product_123.jpg"
→ After: "Product_123"
