Free Online Add Prefix & Suffix Tool
The Add Prefix & Suffix tool lets you insert custom text before and after every line in a multiline list. Instead of editing lines one by one, you can process the entire list instantly.
This can be useful for formatting URLs, keywords, filenames, code snippets, HTML elements, product identifiers, database values and many other forms of line-based text.
What Is a Prefix?
A prefix is text added before existing content.
For example, adding the prefix
#
to the word
marketing
creates
#marketing.
What Is a Suffix?
A suffix is text appended after existing content.
For example, adding
.html
after
about
creates
about.html.
Add a Prefix to Every Line
Paste your multiline content into the input box and enter any custom prefix. The tool adds that prefix before each applicable line. This is useful for hashtags, bullets, URLs, commands, labels and structured text.
Add a Suffix to Every Line
Enter suffix text to append the same value after every applicable line. Common examples include file extensions, punctuation, closing HTML tags, delimiters and query parameters.
Add Prefix and Suffix at the Same Time
You can use both fields together to wrap every line. For example, a double quote can be added before and after each item to create quoted values. Brackets, parentheses and HTML tags can also be applied in the same way.
Add Text to Every Line for Developers
Developers can use prefix and suffix formatting when preparing arrays, HTML list items, SQL-related text, configuration values, command lists or other structured content. Always review generated output before using it in production code or database operations.
Format URLs in Bulk
If you have a list of slugs, you can add a domain or directory path before every line. You can also append file extensions, trailing slashes or query strings when required.
Format Keyword Lists
Keyword lists can be wrapped in quotation marks, prefixed with hashtags or given custom labels. This can save time when preparing content for spreadsheets, documents or other workflows.
Browser-Based Processing
In this implementation, prefix and suffix processing runs directly in the browser with JavaScript. If you later add server-side processing, analytics or third-party scripts, ensure your privacy information accurately describes your production setup.
