Pourquoi utiliser cet outil ?
Numbering every line of a list, script, or code snippet makes it easy to reference or check its content. This tool adds automatic numbering starting from the number of your choice, without doing it manually line by line.
Why it's free
A discreet ad banner covers hosting costs — that's the whole business model. No account to create, no usage limit, no paid tier unlocking the real result. Calculations run in your browser, so your numbers, dates and text never leave your device.
