Whitespace Cleaner
Trim lines, remove extra blank lines, and collapse repeated spaces.
Extra spaces, trailing whitespace, inconsistent tabs, and unnecessary blank lines cause merge conflicts, linting failures, and readability issues. This tool cleans up whitespace problems in one step, with toggles for each type of cleanup — saving you from tedious manual editing across large files.

Frequently Asked Questions
What types of whitespace does this tool clean? ▼
The tool handles: multiple consecutive spaces (reducing to single spaces), trailing spaces at the end of lines, leading spaces at the beginning of lines, extra blank lines, tab characters, and non-breaking spaces. Each type can be toggled independently.
Why does whitespace matter in code? ▼
Inconsistent whitespace causes: merge conflicts in version control, linting errors, subtle bugs in whitespace-sensitive languages (Python, YAML), larger file sizes, and readability issues during code review. Clean whitespace is a sign of professional code.
What are invisible whitespace characters? ▼
Beyond regular spaces and tabs, there are invisible characters like non-breaking spaces (U+00A0), zero-width spaces (U+200B), and byte order marks (BOM, U+FEFF). These can cause bugs and comparison failures that are extremely hard to diagnose visually.
Can I use this to clean data for CSV import? ▼
Yes. Extra whitespace in CSV data can cause import errors and mismatched values. Running your data through this tool before import eliminates trailing spaces and extra blanks that commonly cause problems.
What is trailing whitespace? ▼
Trailing whitespace is spaces or tabs at the end of a line, after the last visible character. It is invisible but wastes bytes, causes diffs in version control, and is flagged by many code style checkers. Most professional code standards require removing trailing whitespace.
