Remove Repeated Characters

This tool scans your text and finds any character that appears consecutively (like 'aa', 'ooo', or '!!!') and reduces it to a single instance ('a', 'o', or '!'). For example, 'Hellooooo World!!!' becomes 'Helo World!'. It's perfect for cleaning up keyboard mash, accidental key presses, exaggerated social media text, or stuttering patterns. The tool processes everything on your device, so your data stays private and secure.

The tool uses an efficient regular expression pattern /(.)\1+/g to detect and remove repeated characters. This pattern matches any character (.) followed by one or more instances of itself (\1+). The g flag ensures it processes the entire text globally. It's a proven, performance-optimized approach that handles texts of any size instantly without requiring server processing.

Use this tool when you need to: (1) Clean up data with accidental character repetitions from keyboard errors, (2) Normalize social media text that uses exaggerated characters for emphasis, (3) Fix stuttering patterns in text imported from speech-to-text systems, (4) Prepare datasets by removing redundant consecutive characters, or (5) Debug code where keyboard mash appears in strings or comments. It's especially useful for data scientists, content moderators, and developers.

Yes! Click the Upload button in the input area to load .txt or .md files directly. The tool reads your file on your device (never uploads to a server) and populates the input area. After processing, click Download to save the cleaned text as a new file with a timestamp. This file I/O feature is perfect for batch cleaning large documents, logs, or datasets without copying and pasting.

Batch mode processes each line of your input independently, applying character removal to every line separately. This is useful when you have a list or dataset where each line should be cleaned individually. For example, if you have a list of usernames or product names with repeated characters, batch mode ensures each item is processed correctly. Toggle it ON in the options section when working with multi-line data.

Yes, the tool is case-sensitive by design. This means 'A' and 'a' are treated as different characters. For example, 'Aa' will remain 'Aa', but 'AA' becomes 'A' and 'aa' becomes 'a'. This ensures intentional case variations are preserved while removing only true consecutive duplicates. This is important for maintaining proper capitalization in names, acronyms, and formatted text.

Yes, the tool removes all consecutive duplicates equally, including spaces, punctuation, and special characters. So 'Hello World' (with double spaces) becomes 'Hello World' (single space), and '!!!' becomes '!'. This comprehensive approach ensures clean, normalized text. If you have multiple spaces or repeated punctuation that are intentional, process selectively or use batch mode to control which lines are affected.

Absolutely. This tool uses 100% client-side processing, meaning all text manipulation happens in your browser on your device. No data is ever sent to any server. Your files and text never leave your computer. This privacy-first approach ensures maximum security and speed, especially important when working with sensitive data, confidential documents, or personal information.

Common use cases include: Data cleaning - Remove keyboard errors from datasets and CSV files; Social media moderation - Normalize exaggerated text like 'Coooool!!!' to 'Cool!'; Text preprocessing - Clean data before NLP or analysis tasks; Code cleanup - Fix keyboard mash in comments, strings, or test data; Content formatting - Normalize user-generated content with excessive punctuation or spacing; Debug logs - Clean up repetitive characters in log files for better readability.

Unlike generic text cleaners, this tool specifically targets consecutive duplicates while preserving everything else. Most tools either remove all duplicates (including non-consecutive ones) or require complex regex knowledge. Our tool offers: Smart consecutive-only detection, batch mode for datasets, comparison view to see exactly what changed, detailed statistics showing character reduction, and file I/O for processing documents. It's purpose-built for this specific task with a user-friendly interface requiring zero technical knowledge.
