How it works

This tool normalizes whitespace in your text by applying one or more transformations. Processing happens entirely in your browser — nothing is sent to a server.

Available options:

• Collapse multiple spaces: replaces runs of two or more consecutive spaces with a single space. For example, "hello   world" becomes "hello world".
• Trim lines: strips leading and trailing whitespace from every line.
• Remove blank lines: filters out lines that are empty or contain only whitespace.
• Tabs to spaces: converts each tab character to a single space. Combined with "Collapse multiple spaces", this effectively replaces tabs with one space.
• Remove trailing newlines: strips blank lines from the end of the text.

Common use cases

• Cleaning pasted content: text copied from web pages or PDFs often contains irregular spacing that needs tidying up.
• Code formatting: normalize indentation by converting tabs to spaces and trimming trailing whitespace.
• Data preparation: clean up CSV or TSV data, log files, or exported text before further processing.
• Writing and editing: remove accidental double spaces and blank lines from drafts or manuscripts.
