Frequently Asked Questions
Can I control how the numbers are formatted?
Yes! You can choose how many digits are padded (e.g., 01, 001) and select from common delimiters like colon, dot, dash, or tab.
How does line number padding work?
You can choose a minimum padding (e.g., 2 for 01, 3 for 001). However, if
your input has thousands of lines, the tool will automatically increase the padding to fit the
highest line number. For example, even if you choose 2-digit padding, 1000 lines will be numbered as
0001 through 1000 to maintain alignment.
Are empty lines numbered?
Yes, every line gets a number, even if it's empty. You can trim or remove those lines beforehand with our other tools.
Does this upload my text?
