CLEAN Formula Syntax
Example Use Case
Removing non-printable characters from text for cleanup
Understanding the CLEAN Formula
The CLEAN function in Excel strips non-printable characters (ASCII 0-31) from text, tidying up data imported from other sources. It’s a cleanup tool for removing hidden control characters—like line feeds or tabs—that mess up display or processing.
CLEAN(A1) with 'Hello' + CHAR(7) (bell) returns 'Hello', dropping the non-printable. It takes a text string, leaving printable characters intact—perfect for prepping messy data.
Why Use CLEAN?
CLEAN fixes invisible glitches—think imported text or legacy system outputs. Its focus on non-printables ensures clean, usable strings, smoothing out data for analysis or display.
Example with Sample Data
| Text | Formula | Result |
|---|---|---|
| 'Hello' + CHAR(7) | =CLEAN(A1) | Hello |
| 'Data' + CHAR(13) | =CLEAN(A1) | Data |
| 'Text' + CHAR(9) | =CLEAN(A1) | Text |
CLEAN purifies: drops CHAR(7) from 'Hello'. It’s a text purger.
