Add Prefix and Suffix to Lines

Free Add Prefix and Suffix to Lines Tool — Bulk Text Wrapping for Any Use Case

Adding the same text before and after every line in a list is one of the most repetitive tasks in text editing — and one of the most immediately automatable. Whether you need to wrap each line in HTML tags, add single quotes around items for a SQL query, prefix every line with a file path, append a domain to a list of usernames, or surround each item with any other consistent text pattern, doing it manually for even a short list is tedious work that invites errors. Our free add prefix and suffix tool applies any text before and after every line simultaneously, transforming an unnumbered list into a correctly formatted output in under a second, regardless of how many lines it contains.

Processing is entirely browser-based. Your text never leaves your device, making this tool appropriate for any list content including customer data, internal identifiers, source code, and proprietary text.

SQL Queries — The Most Popular Use Case

The single most common reason people reach for a prefix and suffix tool is to prepare lists for SQL queries. SQL IN clauses require text values to be wrapped in single quotes: WHERE username IN ('alice', 'bob', 'charlie', 'dave'). If you have a list of usernames, email addresses, or any other string values — one per line in a spreadsheet column or text file — converting that list to properly quoted SQL values requires adding a single quote at the beginning and end of each item. Set prefix to a single quote, set suffix to a single quote, and the tool wraps every line. Combine the output with our List to Comma Separated tool and you have a complete, ready-to-use SQL IN clause.

SQL INSERT statements represent another common application. Bulk inserting data from a list often requires formatting each row as ('value1', 'value2', ...) with appropriate quotation. Adding the necessary quoting and SQL syntax around each row's values using prefix and suffix transformation significantly reduces the manual formatting work before a bulk insert operation.

HTML and Markup Generation

When generating HTML lists, tables, or other markup from plain text data, the prefix-and-suffix pattern is one of the most efficient approaches. To convert a list of items into an HTML unordered list, set the prefix to <li> and the suffix to </li>. Each item becomes a properly tagged list element that you can paste between <ul> and </ul> tags. For table rows, set the prefix to <tr><td> and the suffix to </td></tr> and you get table markup for each item in seconds.

Generating option elements for HTML select dropdowns from a list of choices is another high-value application. Set prefix to <option value="and suffix to ">...</option> — though this specific case may be better handled with a more structured approach, the general pattern of wrapping lines in opening and closing tags covers a wide variety of HTML generation needs that arise regularly in web development, template creation, and static site content preparation.

Markdown and other lightweight markup formats also benefit from this approach. Turning a list of links into Markdown link syntax, wrapping code snippets in code fence markers, or adding blockquote prefixes to lines of a quotation are all achievable through the prefix and suffix tool with the appropriate delimiter characters.

File Paths and System Administration

System administrators and DevOps professionals frequently work with lists of filenames, server names, or identifiers that need to be transformed into full paths, commands, or configuration entries. A list of server hostnames might need to become a list of SSH commands: prefix ssh user@ and suffix (nothing) turns each hostname into a ready-to-execute SSH connection command. A list of filenames might need a full directory path prepended to become absolute paths. A list of usernames might need to become full email addresses by appending a domain suffix like @company.com.

Shell scripting often requires preparing input for commands that expect a specific format. Creating a list of files to be processed, a list of packages to be installed, or a list of services to be restarted with the appropriate command prefix is faster with our tool than writing a loop or manually editing each line. The output can be pasted directly into a terminal, shell script, or configuration file.

Programming and Development Workflows

Code generation is one of the broader applications that the prefix and suffix tool enables for developers. When you need to turn a list of values into a set of constant declarations, enum members, or array entries, adding the appropriate programming language syntax as prefix and suffix transforms the raw values into valid code. A list of color names might become enum members with a language-specific prefix and trailing comma suffix. A list of error codes might become constant declarations with the declaration syntax wrapped around each value.

CSS development benefits from this approach when creating utility classes or custom properties from a design token list. A list of spacing values can become CSS custom property declarations by setting prefix to --spacing- and suffix to: [value]; (with the value itself as each line). Icon font class names can be wrapped in the appropriate CSS selector syntax. Color values can be prepared for insertion into a stylesheet or design system file.

Content Management and Data Preparation

Content teams and data analysts use prefix and suffix tools when preparing data for import into systems with specific formatting requirements. A list of product SKUs might need to be prefixed with a category code to create full product identifiers. A list of tags might need to be wrapped in the tag delimiter syntax expected by a specific CMS. A list of customer IDs might need to be formatted as API endpoint URLs by prepending the base URL.

Bulk renaming operations for files, database records, or content items often involve adding consistent text to existing identifiers. If you have exported a list of current names and need to prepare a list of new names that follow a different naming convention — adding a department prefix, appending a year suffix, or applying any other consistent transformation — the prefix and suffix tool handles the mechanical part of the transformation, leaving you only the decision of what text to add.

How the Tool Works

The processing logic is simple and transparent: for each line in your input, the tool prepends your specified prefix text and appends your specified suffix text, then outputs the result with the same line structure as the input. No other modifications are made — the original content of each line is preserved exactly between the prefix and suffix additions. Empty lines in the input receive the prefix and suffix applied just like content lines, unless the tool has a specific option to skip empty lines.

Whitespace in the prefix and suffix fields is treated as literal characters — if you include a space before or after your prefix or suffix text, that space will appear in the output. This is intentional and useful: you might want a space between your prefix and the line content, or no space at all depending on the formatting context. The tool gives you exact control over the characters that appear in the output.
