Increment controls the step size. Setting it to 1 counts 1, 2, 3… Setting it to 2 counts 2, 4, 6… Setting it to 10 counts 10, 20, 30… You can even use negative increments to count down!

After ‘z’ (26 items), the tool continues with ‘aa’, ‘ab’, ‘ac’… ‘zz’, ‘aaa’, and so on. This follows the same pattern as Excel column labels.

Roman numerals work for values 1-3999 (I to MMMCMXCIX). If you exceed this range, the tool automatically falls back to regular numbers.
