How Prefix / Suffix Adds to Lines Works

You paste your text (one item per line), choose the prefix and/or suffix you want to apply, and generate the updated output. The tool processes the input line by line, optionally trimming whitespace first and optionally leaving blank lines untouched so your spacing stays readable.

Step-by-Step

• 1) Paste your input: Add a list of items, URLs, names, SKUs, or any multi-line text into the input box.
• 2) Enter a prefix: Add characters that should appear before every line (for example - , > , or ").
• 3) Enter a suffix: Add characters that should appear after every line (for example ;, ,, ", or )).
• 4) Choose line endings: Keep the original line endings automatically, or force LF/CRLF for consistent output across systems.
• 5) Generate and copy: Click Generate, then copy the result or download it as a text file.

Key Features

Add a prefix, a suffix, or both

Apply any text around each line, from simple bullets to complex wrappers like JSON keys, Markdown quotes, or shell arguments. If you only need one side, leave the other field blank.

Whitespace control

Enable optional line trimming to remove leading and trailing spaces before the prefix/suffix is applied. This is useful when you paste data from spreadsheets or emails that often contain accidental whitespace.

Blank-line handling

Keep empty lines unchanged when you want visual separation between blocks, or turn the option off if you need a strictly uniform transformation across every line.

Line ending compatibility

Work smoothly with Windows and Unix environments by choosing an output line ending. Auto mode detects the most common line ending in your input so the generated content matches your source.

Copy and download workflow

Get the output in a copy-ready textarea and a one-click download button. This makes it easy to drop the result into editors, terminals, documentation, or ticketing systems.

Use Cases

• Markdown lists: Add - or * as a prefix to turn plain lines into bullet points for README files.
• Quoted strings: Add a prefix and suffix of " to create quoted items for JSON, YAML, or programming language arrays.
• CSV and SQL preparation: Add a suffix comma to produce comma-separated values, or wrap values for SQL IN (...) clauses.
• Configuration snippets: Prefix each line with an indentation or a key pattern to build config blocks quickly.
• Command-line arguments: Prefix each line with flags like --include= or --path= when preparing batch commands.
• HTML attributes or tags: Add prefixes and suffixes that wrap items in simple markup like <li> and </li>.
• Quoting for support tickets: Prefix with > to quote log lines or user messages in a consistent format.

Because it operates line by line, the tool is especially effective for list-oriented tasks where you want a consistent wrapper applied quickly and safely.

Optimization Tips

Decide how to treat blank lines

If your input contains intentional spacing, keep the “Leave empty lines unchanged” option enabled. For machine-validated files where every line must match a pattern, disable it so even blank lines get wrapped consistently.

Trim before you wrap

If you notice uneven alignment or unexpected spaces in the result, enable trimming. This removes hidden whitespace that often causes issues in scripts, configuration files, or strict parsers.

Match the target environment’s line endings

If you are pasting into a Windows-native editor or a repository that enforces CRLF, choose CRLF. If you are working in Linux, Docker, or most CI pipelines, choose LF for predictable diffs.
