Add the same text before, after, or around multiple lines without editing them one by one. FreeProKit’s Add Prefix / Suffix to Lines tool applies reusable text to every non-empty line or to every line in a text block, making it useful for quotes, commas, bullets, URL prefixes, labels, markup, commands, and other repeatable line formatting. The tool runs with JavaScript in your browser, and FreeProKit describes this browser-processing workflow as local unless a live server check is explicitly identified.
What Is Add Prefix / Suffix to Lines?
Add Prefix / Suffix to Lines is a batch text-formatting tool for multiline content. A prefix is reusable text placed before a line, while a suffix is reusable text placed after it. Using both lets you wrap each selected line with opening and closing text.
The main advantage is consistency. Instead of repeating the same edit across a long list manually, you define the repeated text once and apply it across the block.
How to Add a Prefix or Suffix to Multiple Lines
- Paste or enter the multiline text you want to format.
- Enter the reusable text you want before lines, after lines, or on both sides.
- Choose whether to apply the change to every non-empty line or to every line.
- Run the tool and inspect the transformed output.
- Copy or download the finished result using the available output controls.
What Is a Prefix?
A prefix is text added to the beginning of a line. For example, adding “- ” before “Apples” creates “- Apples”. Prefixes are useful for bullets, labels, domains, commands, path fragments, opening quotes, or opening markup.
What Is a Suffix?
A suffix is text added to the end of a line. Adding a comma after “Apples” creates “Apples,”. Common suffixes include commas, semicolons, extensions, closing quotes, brackets, or tags.
Every Line vs. Every Non-Empty Line
FreeProKit lets the transformation target every non-empty line or every line. Use the non-empty option when blank rows are meaningful separators and should stay blank. Use every line when blank rows also need the repeated text.
Common Ways to Use the Tool
Add bullets or labels
Place a dash, marker, category name, or other repeated label before each line for consistent list formatting.
Add commas or semicolons
Append the same delimiter to every selected line when preparing a list for another workflow. Review the final item if the destination format has special rules for trailing delimiters.
Wrap lines with quotes or markup
Use a prefix and suffix together to place opening and closing text around each line. This is convenient for preparation, but the tool does not replace syntax validation or special-character escaping.
Build full URLs from paths
If you have a list of paths or slugs, a shared site prefix can be added to each selected line. Check for duplicate slashes and lines that already contain complete URLs.
How It Differs from Find and Replace
Prefix/suffix editing changes line boundaries. Find and replace changes matching text wherever it appears.
If you need to replace repeated words or phrases instead of adding text to line starts or ends, use Find & Replace Text.
Useful Line-Cleanup Workflow
For messy lists, clean the content before applying final formatting. You can remove duplicate entries, sort the lines, filter unwanted rows, or remove blank lines first.
Try Remove Duplicate Lines, Sort Lines, Line Filter Tool, or Empty Line Remover before the prefix/suffix step.
Privacy and Processing
The live FreeProKit page identifies this as a JavaScript browser tool and states that uploaded files are processed in the browser unless a tool clearly identifies a live server check. This line transformation is therefore presented as a browser-processing task rather than a live website or domain lookup.
Important Limitations
- The tool adds repeated text mechanically and does not validate the syntax of code, SQL, CSV, JSON, HTML, URLs, or commands.
- The live public description does not claim automatic detection of an existing prefix or suffix.
- Special characters inside the original lines are not described as being escaped automatically.
- Blank-line behavior depends on the selected every-line or non-empty-line mode.
Frequently Asked Questions
What does Add Prefix / Suffix to Lines do?
It adds reusable text to the beginning of lines, the end of lines, or both. FreeProKit’s live description states that the transformation can be applied to every non-empty line or to every line in a text block, which makes it useful for bulk line formatting.
Can I use this tool to add text before every line?
Yes. Adding text before a line is a prefix operation. Typical examples include bullet markers, labels, domains, opening quotes, path fragments, or commands. Review the output when some lines may already contain the same starting text.
Can I add text after every line?
Yes. Text added after a line is a suffix. Common examples include commas, semicolons, closing quotes, closing brackets, file extensions, or repeated notes. The resulting text should still be checked if it will be used in code or structured data.
What is the difference between every line and every non-empty line?
Every line includes blank rows in the transformation. Every non-empty line leaves blank lines unmodified. The non-empty option is useful when blank rows are being used to separate groups or paragraphs and should remain visually empty.
Can I wrap every line with quotes or other characters?
Yes, a prefix and suffix can be used together to place reusable text on both sides of each selected line. This is convenient for basic quoting or markup preparation. The tool should not be treated as a format validator or special-character escaping utility.
Can I use it to create a SQL, CSV, or code list?
It can help prepare line-based text by adding quotes, commas, brackets, or other repeated characters. However, the live page does not claim SQL, CSV, JSON, or programming-language validation. Always inspect escaping, delimiters, null values, and the final item before using the output.
Does the tool process my text in the browser?
The live page identifies this as a JavaScript browser tool and states that uploaded files are processed in the browser unless a live server check is clearly identified. That matches the nature of this line-based text transformation.
What should I use if I need to number or filter lines instead?
Use a tool built for that specific transformation. FreeProKit has a Line Numbering Tool for configurable line numbers and a Line Filter Tool for keeping or removing lines based on contains, starts-with, ends-with, or regular-expression matching.
