What common text problems can the cleaner fix, and when should I use each operation?

Text cleaning solves real-world data quality problems: (1) Extra whitespace (multiple spaces, trailing spaces, tabs mixed with spaces) — common when copying from PDFs, emails, or websites. (2) Inconsistent line breaks (CR, LF, CRLF mix) — files from different operating systems use different line endings; normalize to your platform's standard. (3) Empty lines — data exports often have blank separator rows; strip them to compact the data. (4) HTML tags in scraped text — web scraping often leaves <p>, <br>, <div> tags; strip them to get clean plain text. (5) Smart quotes and special characters — Word processors replace straight quotes with "smart" curved quotes, which can break code and CSV parsing; convert them to ASCII equivalents. (6) Unicode normalization — some characters have multiple Unicode representations (e.g., é can be a single character U+00E9 or e + combining accent U+0065 U+0301); normalize to NFC or NFD form. Clean your text before importing into databases, running through NLP pipelines, or committing to version control.
