Whitespace Cleaner

Frequently Asked Questions

It removes all leading and trailing spaces (and tabs) from each individual line. The content between the line edges is unchanged. This is equivalent to calling trim() on each line in PHP, or .strip() in Python.

It replaces any run of two or more consecutive space characters (within a line) with a single space. It does not collapse newlines, only horizontal spaces. Use it to clean up copy-pasted text from PDFs, HTML, or word processors.

This applies three operations in sequence: (1) trim each line, (2) collapse extra spaces, and (3) collapse multiple consecutive blank lines to a single blank line. This preserves paragraph structure while removing messy whitespace — the most common cleaning task.

How It Works

Paste Messy Text

Paste text with inconsistent whitespace, extra spaces, blank lines, or tabs into the input area on the left.

Click an Operation

Each button applies a specific regex-based transformation: trim, collapse spaces, remove blank lines, convert tabs, or remove all whitespace.

See & Copy Result

The cleaned text appears in the output card with a before/after character count. Click Copy to grab it. Reset restores the original.

Common Use Cases

PDF Copy-Paste Cleanup

Text copied from PDFs often has extra spaces and broken line breaks. Use Trim + Collapse to restore clean paragraphs in seconds.

Code Pasting Normalization

Convert tabs to spaces (or vice versa) when migrating code between editors with different indentation settings to prevent syntax errors.

CSV & Data Prep

Trim leading and trailing spaces from each value in a CSV export before importing to a database, preventing mismatched lookups and key errors.

Article & Blog Formatting

Remove excessive blank lines pasted from a Word document into a CMS. "Collapse multiple blank lines" preserves paragraph breaks while removing extras.

Email Template Cleanup

Strip extra whitespace from copy-pasted email content before sending. Clean whitespace prevents unexpected rendering differences across email clients.
