Frequently asked questions

What is Increment numbers?

Add (or subtract) a fixed amount to every number in your text.

When would I actually use this?

Cleaning up a paste before it goes anywhere: stripping duplicates from a list, normalising case, removing accents for a filename, or sorting lines.

What is the most common mistake?

Sorting text as if it were ASCII. Accented letters land after Z in a byte sort, which puts "Zurich" before "Émile" and produces a list no reader will accept.

How is Increment numbers different from Add line numbers?

They sit next to each other but answer different questions: Add line numbers is the one to open when you need it to prefix every line of your text with a sequential line number. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Remove line numbers is the closest one after this: Strip leading line numbers (1. 2) 3:) from every line.

Where do the figures come from?

Transformations use the browser's Unicode-aware string handling, so case changes and sorting respect the locale rather than byte order. Nothing is truncated: what comes out is the whole of what went in.
