💡 Tips

Use \s+ to match all whitespace types
Combine with trim() for complete normalization
Useful for cleaning pasted text
Test with actual data to avoid over-normalization

⚠️ Common Pitfalls

Does not handle other whitespace (tabs, newlines)
May want to preserve intentional spacing (code, tables)
Consider trimming leading/trailing spaces too
Different from \s+ which matches all whitespace
