Microsoft Excel provides a useful function called CLEAN, which is designed to remove non-printable characters from text data. By the end of this article, you’ll understand how to effectively use the CLEAN function in your spreadsheets.
Key Takeaways
- The CLEAN function removes non-printable characters from text.
- It is especially useful for cleaning up imported data or data copied from other sources.
- The syntax is simple: CLEAN(text), where “text” is the input you want to clean.
How to Use the CLEAN Function in Microsoft Excel
Step 1: Open Your Excel Worksheet
Launch Microsoft Excel and open the worksheet where you want to apply the CLEAN function.
Step 2: Identify the Cell with Text
Locate the cell containing the text you want to clean. For instance, suppose you have text in cell A1.
Step 3: Select a New Cell
Click on an empty cell where you want to display the cleaned text. For example, select cell B1.
Step 4: Enter the CLEAN Function
Type the following formula into the selected cell:
=CLEAN(A1)
This formula will remove any non-printable characters from the text in cell A1.
Step 5: Press Enter
After entering the formula, press Enter on your keyboard. The cleaned text should now appear in cell B1.
Step 6: Copying the Formula (Optional)
If you have more text to clean, you can copy the formula down to other cells in the same column. Simply click and drag the fill handle (the small square at the bottom right corner of the cell) downwards.
Practical Example
Suppose you have a list of names imported from an external database, and some names contain non-printable characters:
- Original: “John Smith”
- Cleaned: “John Smith”
Using the CLEAN function, the non-printable characters will be efficiently removed.
Common Use Cases for CLEAN
