What this tool does not do / Limits
This pads whole numbers only. Decimals and non-numeric input are reported as errors.
Frequently asked questions
What if the number is already longer than the width?
It is left unchanged; padding never removes digits.
Are leading zeros kept as text?
Yes. Copy the result as text, because a spreadsheet may drop leading zeros if it treats it as a number.
