Frequently Asked Questions
What can I do with the text formatter? â–¼
You can perform dozens of text manipulations: convert case (uppercase, lowercase, title case, sentence case), sort lines alphabetically or by length, remove duplicate and empty lines, trim whitespace, remove punctuation, reverse text, add line numbers, add prefixes/suffixes to lines, and extract specific patterns like emails or URLs.
Does it work with large text files? â–¼
Yes! Since all processing happens locally in your browser using JavaScript, there are no file size limits imposed by servers. You can format text files with millions of lines. Performance depends on your device, but modern computers handle even very large texts instantly.
Can I remove duplicate lines while preserving original order? â–¼
Yes! Our duplicate removal algorithm maintains the original order by keeping the first occurrence of each unique line and removing subsequent duplicates. This is different from sort + unique operations which change the order. Perfect for cleaning lists while maintaining priority or chronological order.
What's the difference between Title Case and Sentence case? â–¼
Title Case Capitalizes The First Letter Of Every Word - used for headlines, book titles, and section headings. Sentence case only capitalizes the first word of each sentence (and proper nouns) - used for normal writing, descriptions, and body text. Example: "The Quick Brown Fox" (Title) vs "The quick brown fox" (Sentence).
Is my text data private and secure? â–¼
Absolutely! All text processing happens entirely in your browser using client-side JavaScript. Your text never leaves your device - it's not uploaded to any server, stored anywhere, or transmitted over the internet. This makes it completely safe to format sensitive data like customer lists, passwords, or confidential information.
