Add Prefix/Suffix

What Is the Add Prefix/Suffix Tool?

The Add Prefix/Suffix tool lets you type in any text you want and automatically attach it to the start, the end, or both ends of every line in your input. You set the prefix value, the suffix value, click the button, and the whole block updates at once. It is a straightforward bulk text operation that would take a surprising amount of manual work to do by hand, especially across longer lists.

The main use is repetitive text editing tasks where the same characters or words need to appear on every line. Developers, data people, and writers who work with structured content tend to find it most useful, though the range of actual uses is wider than it first sounds.

How to Use This Tool

1. Paste or type your text into the input box above. Each line will be treated separately.
2. Type whatever you want added to the front of each line into the Prefix field. Type what you want added to the end of each line into the Suffix field. You can fill in one, the other, or both.
3. Click the Add Prefix/Suffix button and the tool applies your text to every line in the output.
4. Copy the result using the Copy button, or select and copy manually.

When Would You Use This?

• Wrapping a list of values in SQL-style quotes or brackets before inserting them into a query, so each item goes from value to "value" without editing them one by one.
• Adding a consistent tag, label, or identifier to the beginning of each line in a list, such as turning a plain name list into a formatted data set with a category prefix on every entry.
• Appending punctuation, closing tags, or a repeated string to the end of every line in a block of text that was exported or copied without it.

Also comes up for things like adding bullet characters, markdown syntax, or HTML tags to lines of content in bulk. Honestly, once you have this tool open it starts finding its own uses fairly quickly.

Frequently Asked Questions

What is a prefix and suffix in text editing?

A prefix is text added to the beginning of something, and a suffix is text added to the end. In the context of this tool, that means whatever you type into the Prefix field gets placed at the start of each line, and whatever is in the Suffix field gets placed at the end. So if your prefix is - and your line is item one, the output is - item one.

Can I add a prefix without adding a suffix, or vice versa?

Yes. The fields are independent. Leave the one you do not need empty and fill in only the one you want. The tool applies whatever is present and ignores empty fields.

How do I add the same text to multiple lines at once?

Paste all your lines into the input box, type your repeated text into the Prefix or Suffix field, and click the button. Every line gets the same text added in one go. This is the main thing the tool is built for.

Can I use this to wrap lines in quotes?

Yes. Set the Prefix to a quote character and the Suffix to a quote character and every line will come out wrapped. Useful for preparing lists of strings for code, spreadsheets, or anywhere quoted values are expected.

Does it work with special characters and symbols?

Yes. You can type any characters into the prefix or suffix fields, including symbols, punctuation, spaces, or HTML tags. Whatever you type in is what gets added, exactly as written.

How do I add a prefix to every line in Excel or Google Sheets?

In spreadsheet applications you would typically use a formula like =CONCAT("prefix",A1) or a find-and-replace with regex. But if you have the content as plain text rather than in a spreadsheet, pasting it into this tool is faster. Copy your column, paste here, add prefix/suffix, paste the result back in.

Can I add a prefix to lines in a text file?

Open the file, select all, copy, paste into this tool, run it, then copy the output back into the file. That is the quickest path without needing a script or a text editor with macro support.

Will blank lines in my text also get the prefix and suffix added?

Blank lines are still lines, so depending on the tool's behavior they may receive the prefix and suffix characters even with no content between them. Worth a quick check on the output if your text has empty rows scattered through it.

Is there a limit to how many lines I can process?

No hard limit is set. For typical tasks like a list of values, a CSV column, or a block of content, it works without issue.
