Remove Suffix from Text Lines
Precision removal of text, patterns, or characters from the end of every line.
Configuration
Clean Line Endings: Strip What You Don't Need
In data processing, code refactoring, and text formatting, trailing characters cause problems. A semicolon at the end of every line when you're converting JavaScript to Python. File extensions on a list of filenames when you need just the names. Trailing commas in CSV data that break imports. These small suffixes add up to big headaches when you're dealing with hundreds or thousands of lines.
The Remove Suffix from Text Lines tool is your precision cleanup assistant. It offers three powerful removal modes: remove specific strings (like ";" or ".txt"), use regex patterns for advanced matching (like \.\w+$ to strip all file extensions), or simply delete the last N characters from every line. The tool processes locally in your browser, handles files up to 1MB+, and provides real-time statistics showing exactly how many lines were modified and how many characters were removed.
Why Remove Suffixes?
- ✓Code Conversion: Convert between programming languages by removing syntax differences (semicolons, type annotations, etc.)
- ✓Data Preparation: Clean CSV exports, remove trailing delimiters, strip file extensions for bulk renaming operations.
- ✓Log Processing: Remove timestamps, severity tags, or debug symbols from log file endings to focus on message content.
- ✓Text Cleanup: Strip trailing punctuation, ellipses, or unwanted characters from pasted content instantly.
Common Use Cases
Code Refactoring
Remove semicolons when converting JavaScript to Python, strip SQL terminators, or clean trailing commas from code arrays and objects for cleaner syntax.
CSV & Data Cleaning
Remove trailing commas from CSV exports, strip pipe separators, or clean file extensions from filename lists in bulk datasets.
File Renaming Prep
Strip file extensions (.jpg, .txt) from a list of filenames to prepare for bulk renaming or reformatting operations.
Log Processing
Remove trailing timestamps, severity indicators, or debug symbols from the end of log lines to focus purely on the message content.
