Category
This function falls under Excel Text Functions, which are essential tools for manipulating and working with text strings.
Excel CLEAN Syntax
=CLEAN(text)
The CLEAN function syntax has only one argument:
- text: The text from which you want to remove non-printable characters.
Excel CLEAN Parameters
Let’s dive deeper into the parameter:
- Text: This represents the string that you want to clean. It can be a hard-coded string, a cell reference, or a result of another function. Note that CLEAN will remove characters that are non-printable in the 7-bit ASCII code range (0 to 31).
Return Value
The CLEAN function returns a text string with all non-printable characters removed.
Examples
To illustrate how CLEAN works, let’s look at a couple of examples:
=CLEAN("Hello World!") will simply return Hello World! because there are no non-printable characters.
=CLEAN(CHAR(7)&"Alert") will return Alert, removing the non-printable bell character (ASCII 7).
Use Cases
The CLEAN function is particularly useful in scenarios where data is imported from other sources, which might contain non-printable characters that can interfere with data analysis, or when preparing data for export to systems that do not support such characters. Here are some tips for using the function effectively:
- Always use CLEAN on text data imported from external sources.
- Combine CLEAN with TRIM to remove extra spaces and non-printable characters in one go.
Common Errors
Errors are rare with the CLEAN function, but problems can arise if expectations for what it removes are not set correctly. CLEAN only removes non-printable ASCII characters, so some unwanted characters might remain if they are outside this range.
Compatibility
The CLEAN function is compatible with all versions of Excel. However, it’s worth noting that the function’s behavior and the range of characters considered non-printable may vary slightly across different operating systems and regional settings.
Conclusion
The CLEAN function in Excel is a simple yet powerful tool for ensuring your text data is free from non-printable characters, making it more usable and presentable. From cleaning data imported from another system to preparing data for export, it’s an essential function for anyone working with text in Excel.
