How does the text cleaner remove duplicates?

The text cleaner identifies duplicate lines by comparing each line with all previous lines. You can choose case-sensitive or case-insensitive duplicate detection. When duplicates are found, only the first occurrence is kept, and subsequent duplicates are removed.

Can I use custom regex patterns to clean text?

Yes! The advanced text cleaner supports custom regex patterns. You can enter a regex pattern and specify a replacement string. This allows you to perform complex text transformations like removing specific patterns, replacing text, or extracting certain content.

What file formats can I export cleaned text to?

You can export cleaned text in multiple formats: plain text (.txt), CSV (.csv), and JSON (.json). The CSV format properly escapes special characters, and JSON format provides structured data output.

Does the text cleaner work with different line separators?

Yes, you can choose from newline, comma, semicolon, pipe, or specify a custom separator. This makes it easy to clean CSV data, delimited lists, or any text with custom separators.

Is my text data secure and private?

Yes, all text processing happens entirely in your browser. Your data never leaves your device and is not stored or transmitted to any server. The tool works completely client-side for maximum privacy and security.

Can I see a live preview of changes as I type?

Yes! The text cleaner features a live preview mode that automatically updates the cleaned output as you type or modify settings. You can also toggle between side-by-side comparison view and output-only view to see changes in real-time.

What advanced cleaning options are available?

Advanced options include: removing URLs, email addresses, numbers, and special characters; Unicode normalization; custom regex patterns; case-sensitive duplicate detection; preserving line order; and sorting lines alphabetically. All options can be combined for comprehensive text cleaning.
