Text tool
Whitespace Cleaner
Trim, collapse, and normalize whitespace with explicit options.
Output
How the whitespace cleaner works
Clean selected whitespace issues without sending text to a server.
With collapse spaces enabled, 'one two' becomes 'one two' while line breaks remain.
Assumptions and limitations
Options that collapse spaces or blank lines can alter intentional formatting, so they are off until selected.
Inputs and results stay in your browser. Blank, invalid, or mathematically undefined inputs show a clean placeholder instead of a broken number.
Practical use
Use this text tool to explore scenarios quickly, then verify important decisions against the original source data or requirements.
Frequently asked questions
Does the whitespace cleaner send my data anywhere?
No. It runs client-side in your browser and makes no network requests.
Why is the result blank or shown as a dash?
One or more inputs are blank, outside the accepted range, or would make the calculation undefined. Check the labels and enter finite values.
Can I use decimal values?
Yes, where decimals are meaningful. Counts that represent whole items may require integers.
