Add Prefix and Suffix to Every Line: Online Bulk Text Editor
What is a Prefix/Suffix Adder? It is a bulk text-processing utility designed to insert specific characters, words, or symbols at the start (prefix) or end (suffix) of every line in a list. Our Bulk Line Editor features advanced filters like line numbering, whitespace trimming, and duplicate removal-making it the ultimate tool for developers preparing SQL queries, CSV data, or code arrays.
What is the "Add Prefix/Suffix" Tool?
The Add Prefix/Suffix tool is a high-speed productivity utility that eliminates the tedious task of manually editing hundreds of rows of data. Whether you are preparing a list of strings for a programming array, wrapping words in quotes for database imports, or adding unique identifiers to a dataset, this tool handles thousands of lines in milliseconds. It provides a surgical way to transform raw, messy text into a perfectly structured format.
Most Popular Use Cases & Transformations
Our users rely on this tool for a variety of "Quick-Fix" formatting tasks. Here are the most common ways to use the Prefix/Suffix engine:
1. Add Quotes Around Lines (SQL & JSON)
One of the most frequent searches is for "wrapping text in quotes." To convert a list of names into a database-ready format, simply add a single or double quote as both the prefix and suffix. This is essential for building SQL IN clauses or JSON string arrays.
Example: Apple → 'Apple'
2. Add Commas at Line Ends (CSV Formatting)
If you have a vertical column of data and need it to be a single-line comma-separated list, add a comma (,) as the suffix. Combine this with our "Remove New Lines" tool (found in our Text Transformation suite) for a perfect CSV output.
Example: Item 1 → Item 1,
3. HTML List Wrapping (<li> Tags)
Web developers often need to turn a plain text list into an HTML list. Set your prefix to <li> and your suffix to </li> to wrap your entire list in list item tags instantly.
4. Bulk Code Commenting
Need to comment out a large block of text or data? Set your prefix to // (for JavaScript/C++), # (for Python/Bash), or -- (for SQL) to transform regular text into non-executable code comments.
Advanced Formatting & Cleaning Filters
Unlike basic tools, All Over Tools provides granular control over how your text is processed before and after adding your prefix or suffix:
Smart Line Numbering
Create organized instructions or indexed logs with one click. Our tool supports multiple professional numbering formats, including "1. line", "1) line", and "[1] line". This is ideal for technical documentation or legal referencing.
Data Cleaning: Trim & Deduplicate
To ensure your final output is clean, use the Trim Lines filter to remove accidental leading or trailing spaces. You can also toggle Skip Duplicate Lines to ensure every entry in your final formatted list is unique-essential for cleaning up marketing lead lists or SEO keyword datasets.
How to Format Your List Instantly
- Paste: Drop your raw list or text block into the input area.
- Configure: Enter your custom Prefix (start) and Suffix (end).
- Apply Filters: Enable line numbering, trim whitespace, or remove duplicates as needed.
- Export: Instantly copy your formatted results or download them as a text file.

Frequently Asked Questions (FAQs)
Can I add line numbers and custom text at the same time?
Yes. You can enable line numbering as a prefix and still add a custom suffix (like a comma) to create a formatted, numbered data set.
What happens to empty lines?
By default, the "Skip Empty Lines" filter is enabled. This ensures your prefix and suffix are only applied to lines that contain actual content, preventing messy formatting on blank spaces.
Is there a line limit for bulk processing?
No. Because the tool processes text locally in your browser (client-side), it can handle tens of thousands of lines without server timeouts, while keeping your data 100% private.
