FAQ
Can I start from 0?+
Yes — the start number is free-form. Negative numbers work too.
Which separators are supported?+
Anything you type — periods (.), colons (:), brackets, etc. Examples: '1. item', '1) item', '[1] item'.
What is digit padding?+
Pads numbers with leading zeros — 01, 02, 03 instead of 1, 2, 3. Aligns better in lists.
Are empty lines numbered?+
Pick between skipping or including empty lines via an option.
Reverse numbering?+
Forward only for now. To reverse, flip line order with [Text Reverse] first, then number.
Good for Excel row numbers?+
Excel's ROW() function may be easier, but this tool is fast for external data without formulas.
