Add a custom suffix to the end of each line.
Append custom text to every line in your content. Perfect for adding commas, semicolons, file extensions, closing tags, or any repeated suffix. Useful for creating SQL arrays, formatting code, adding punctuation, and batch text transformations.

Suffix addition appends a specified string to the end of each line in text. For example, adding a comma suffix to a list transforms item1, item2, item3 (on separate lines) to item1,, item2,, item3, with commas appended. This automation saves time when formatting lists, arrays, or data.
The process iterates through each line, concatenating the suffix to its end. Empty lines may also receive suffixes unless filtered. The result is a uniformly formatted list where every line ends with the chosen suffix, ready for use in code, data files, or documentation.
Suffix addition is common in data preparation and code formatting. SQL array literals require commas after each value, JSON arrays need trailing commas (in some cases), and file lists may require extensions. This tool automates these repetitive tasks, reducing manual editing errors.
Browser-based suffix addition ensures privacy. No data is uploaded to servers, keeping file names, code, or confidential lists secure. Users can safely append suffixes to sensitive content without exposure risks.
SQL query construction benefits from suffix addition. When creating INSERT statements or array literals, values need commas: VALUES (1,2,3,). This tool adds commas to line-separated values, preparing them for SQL queries with correct syntax.
Code generation uses suffix addition for syntax completion. Adding semicolons to JavaScript statements, closing tags to HTML elements, or colons to Python dictionary keys automates formatting. This tool appends required syntax elements to lists of code fragments.
File and path manipulation employ suffix addition. Adding file extensions (.txt, .csv, .json) to a list of file names, or appending directory paths (e.g., /data/) to subdirectories, automates batch renaming or path construction tasks.
Data formatting for CSV or delimited files uses suffix addition. Adding delimiters (commas, pipes, tabs) to values prepares data for CSV export or custom-delimited formats. This tool formats line-separated data into delimited records.
Empty lines receive suffixes unless filtered. If input contains blank lines, they will also get the suffix, potentially creating unwanted entries (just the suffix on a line). Users should remove empty lines before or after adding suffixes.
Last line suffix may be unwanted. In comma-separated lists, the final item often should not have a trailing comma. This tool adds suffixes to all lines uniformly, requiring manual removal of the last suffix if needed.
Special characters in suffixes may need escaping. When adding suffixes containing quotes, backslashes, or regex characters, verify that they are interpreted correctly in target contexts (code, data files).
Large files may process slowly. Appending suffixes to thousands of lines in a browser may take time. For very large datasets, command-line tools (sed, awk) offer better performance.
Remove empty lines before adding suffixes. Preprocess text to eliminate blank lines if they should not receive suffixes. This prevents unwanted suffix-only lines in output.
Manually adjust the last line if needed. For lists where the final item should not have a suffix (e.g., last value in SQL array), edit the last line after suffix addition to remove it.
Verify suffix escaping for target format. Ensure that suffix characters are valid and properly escaped for the intended use case (SQL, JSON, code). Test output in the target environment to confirm correctness.
Combine with other text tools for complete formatting. Use prefix addition, line removal, or trimming tools alongside suffix addition to achieve complex formatting transformations in multi-step workflows.
