Raw text pasted from PDFs, spreadsheets, and emails is often littered with trailing whitespace, inconsistent line endings, and duplicate records.
Clean and standardize text using the Text Cleaner & Normalizer.
Common Text Normalization Operations
- Remove Duplicate Lines: Deduplicate lists while preserving original insertion order or sorting alphabetically.
- Whitespace Normalization: Strip leading/trailing spaces, collapse multiple spaces into one, and remove blank lines.
- Case Conversions: Transform text between camelCase, snake_case, kebab-case, PascalCase, and Title Case.
- Stripping Accents & Diacritics: Normalizing unicode characters (
é$\to$e).
Clean your text blocks with the Text Cleaner & Normalizer.
