Frequently Asked Questions
Can I use both prefix and suffix at the same time?
Yes! You can add text to both the beginning and end of each line simultaneously. Just fill in both the prefix and suffix fields.
What happens to empty lines?
Empty lines are preserved in the output. If you add a prefix or suffix, empty lines will only contain that prefix/suffix text.
Can I use special characters?
Absolutely! You can use any characters including quotes, brackets, HTML tags, or special symbols in your prefix and suffix.
Is there a limit to how much text I can process?
There's no strict limit, but very large texts may take longer to process. The tool handles thousands of lines efficiently.
Can I undo the changes?
The tool doesn't modify your original text. Your input remains unchanged, and the formatted result appears in a separate output area.
