Whitespace Cleaner
Remove extra spaces, tabs, and clean up whitespace.
📘 How It Works
Tab Conversion
Tabs (\t) are replaced with spaces using a simple regex replacement. This standardizes indentation before further processing.
Line Trimming
Each line is processed with trim() to remove leading and trailing whitespace. This cleans up inconsistent indentation and trailing spaces.
Multiple Space Collapse
Regex / {2,}/g matches two or more consecutive spaces and replaces them with a single space. This normalizes word spacing.
Blank Line Removal
When enabled, lines are filtered to remove those where trim().length === 0. This eliminates both empty lines and whitespace-only lines.
Character Statistics
The tool compares input and output lengths, showing exactly how many characters were removed during cleaning.
