Frequently Asked Questions

What can this tool clean?: It trims lines, collapses spaces, normalizes whitespace, removes spaces or blank lines, and replaces tabs.
Does it modify text as I type?: Yes. Output updates immediately whenever input or cleaning options change.
Can tabs be converted to different widths?: Yes. Choose 2, 4, or 8 spaces per tab.
What types of whitespace can be removed?: The tool supports multiple modes: remove leading/trailing spaces, remove all extra spaces (collapse multiple spaces to one), remove all spaces entirely, remove blank lines, remove tab characters, and normalize all whitespace to single spaces.
What is 'normalize whitespace'?: Normalize whitespace replaces all sequences of spaces, tabs, and newlines with a single space. This is useful for cleaning up HTML source, pasted content from PDFs, or text with inconsistent formatting.
Will this break my code formatting?: The 'Remove leading/trailing spaces' and 'Collapse multiple spaces' modes are safe for most code. Use caution with 'Remove all spaces' on code, as it will break syntax. The tool shows a preview before you copy.
Can I remove blank lines only?: Yes. Select the 'Remove blank lines' option to remove empty lines while preserving all other whitespace and formatting.
