String Concatenation is a powerful, free online tool designed to help you quickly add prefix and suffix text to multiple lines at once. This tool is essential for data formatting, CSV file preparation, SQL query generation, code generation, URL building, and any task that requires adding consistent text before or after each line in a list. Perfect for developers, data analysts, content creators, and anyone working with structured text data.
Adding prefixes and suffixes to large lists manually is tedious, time-consuming, and error-prone. Whether you need to wrap each line in quotes for SQL INSERT statements, add HTTP protocol to domain names, append file extensions, or insert delimiters between columns, doing this by hand for hundreds or thousands of lines is impractical. Our String Concatenation tool automates this entire process, ensuring consistency and saving valuable time.
The tool offers two powerful modes: Simple Mode adds prefix and suffix as new columns separated by your chosen delimiter, while Column Merge Mode inserts prefix and suffix around a specific column number in delimiter-separated data. This flexibility makes it perfect for both basic text wrapping and advanced CSV/TSV manipulation where you need precise control over column positioning.
All processing happens entirely in your browser - no data is uploaded to any server, ensuring your information remains completely private and secure. The tool handles lists of any size instantly, with optional duplicate removal to clean your data before processing. It is fast, unlimited, and completely free to use without registration or restrictions. Perfect for preparing data imports, generating code, formatting lists, and any text transformation task.
Simple Mode: Adds prefix and suffix as new columns. Column Merge Mode: Inserts prefix and suffix around a specific column in delimited data. Switch between modes based on your needs - simple wrapping or advanced column manipulation.
Choose any delimiter character - pipe (|), comma (,), tab, semicolon (;), or any custom character. The tool splits and joins your data using the specified delimiter, making it compatible with CSV, TSV, pipe-delimited files, and any custom format you need to work with.
In Column Merge Mode, select exactly which column number to wrap with your prefix and suffix. The tool inserts the prefix before and suffix after the specified column, leaving other columns untouched. Perfect for adding quotes around specific fields in CSV files or wrapping particular columns with SQL functions.
Enable duplicate removal to automatically eliminate duplicate lines before processing. This ensures each unique line is processed only once, preventing redundant entries in your output and keeping your data clean and efficient.
