Add Prefix to Text – Add a Prefix to Every Line Instantly
Working with long lists of text often requires adding the same word, symbol, or character to the beginning of every line. Whether you're formatting code, creating HTML lists, preparing SQL queries, or organizing data, doing this manually can take a lot of time.
The Zeerogpt Add Prefix to Text tool makes the process simple. It lets you add a custom prefix to every line of text instantly, saving time and ensuring consistent formatting. Whether you're a developer, writer, student, or data analyst, this free online tool helps streamline repetitive text-editing tasks.
What Is an Add Prefix to Text Tool?
An Add Prefix to Text tool automatically inserts specified text at the beginning of each line in a block of text. Instead of editing every line individually, you simply enter your desired prefix, and the tool applies it to all lines at once. This is especially useful for batch formatting, coding, and data preparation.
Example Input: Apple Banana Orange
Prefix: -
Example Output: - Apple - Banana - Orange
