Frequently Asked Questions (FAQ)
When do I need text cleaning?
Text cleaning is useful when:
- Text copied from web has excessive whitespace
- Converting multi-line text to single line
- Removing special characters from data
- Normalizing case (uppercase/lowercase)
What is space normalization?
It converts multiple consecutive spaces (spaces, tabs, etc.) into a single space. For example, "Hello World" becomes "Hello World".
What's kept when removing special characters?
Only English letters (A-Z, a-z), numbers (0-9), Korean characters (가-힣), and spaces are kept. All special characters like !, @, #, $ are removed.
What happens when removing line breaks?
All line breaks (\n, \r\n) are replaced with spaces. This is useful for converting multi-line text into a single line.
Can I use multiple options together?
Yes! Select all desired options and they'll be applied in sequence. For example, you can combine space normalization with special character removal.
Can I convert to both upper and lower case?
No. Lowercase and uppercase conversion are mutually exclusive. You can only select one at a time.
