How to Add Prefix and Suffix

This powerful tool allows you to add specific text before (prefix) and after (suffix) every line of your input text. It is extremely useful for formatting code arrays, building SQL queries, or preparing lists for markdown.

Advanced Line Filtering

You can choose to apply your prefix and suffix to all lines, or only to non-empty lines, even lines, or odd lines. Furthermore, you can use conditional rules to only modify lines containing specific words or matching a regular expression.

Practical Use Cases for Prefix & Suffix Tool

Add SQL quotes: wrap column names in backticks for MySQL queries

Create list items: prefix with "- " or "• " for Markdown or plain text lists

Batch rename: add a date prefix or version suffix to file names

CSS class generation: prefix with "." to turn names into selectors

Import formatting: wrap values in quotes for CSV or SQL INSERT statements

Why Developers Use This Tool Daily

Manually editing dozens of lines to add the same prefix or suffix is tedious and error-prone. A single paste and click processes hundreds of lines in milliseconds, with zero risk of missing one.

The tool is especially powerful for bulk data preparation: generating SQL value lists, preparing import files, or formatting code identifiers all in one shot.

Apply Only to Lines That Match a Condition

Advanced mode lets you filter which lines get modified. Apply prefix/suffix only to lines that contain a specific word, or only to lines that match a regular expression.

You can also apply to every Nth line or a custom range (e.g., lines 5–20) — perfect for structured data with repeating patterns.

1. apple
2. banana
3. cherry
4. date

Auto-Numbering Feature

Enable "Add Numbering" to automatically prepend sequential numbers to each line. Choose the format (1. / 1) / (1)) and starting number to match exactly what you need.

Combine numbering with a custom prefix or suffix for even more control — for example, numbered SQL INSERT values or a numbered list with trailing comma.

100% Private: All Processing is Local

Your text never leaves the browser. The tool processes everything client-side using JavaScript, with zero server communication. Paste proprietary data, internal docs, or personal information safely.

Power-User Tips for Prefix & Suffix

1 Use "Prevent duplicate" options when processing data that may already be partially formatted.

2 Combine prefix + suffix to wrap each line in HTML tags: prefix "<li>" / suffix "</li>".

3 Apply to odd/even lines only to format alternating data structures easily.

4 Use regex conditions to target only lines that follow a specific pattern (e.g., lines starting with a digit).

Common Text Patterns You Can Build

Here are some patterns that users generate in seconds: SQL value tuples, Markdown list items, PHP array strings, CSS class selectors, bash array elements, and environment variable definitions.

Each of these normally requires a script or manual editing. With this tool, it is a matter of setting a prefix and suffix once and clicking Process.

'value1',

'value2',

- item one

- item two

.class-a {}

.class-b {}

Technical Details: Unicode and Large Files

The tool supports full Unicode — emojis, accented characters, CJK, and RTL scripts all work as expected. Line detection handles both LF (Unix) and CRLF (Windows) line endings.

Performance: tested with 10,000+ lines with no noticeable delay. For very large jobs (100K+ lines), consider splitting into batches for smoother performance.
