Two things you might be doing with pasted text
The tools here split by what you want back.
Measuring it. The character, word and page counter tells you how long something is — and which of the three answers you need depends entirely on who is asking. Social platforms count characters. Editors and clients count words. Universities and translation agencies in much of Europe count standard pages, which is a character count divided by a fixed number, and is why a thesis requirement of “60 pages” is not a page count at all.
Reshaping it. The case converter moves between camelCase, snake_case, kebab-case, Title Case and the rest — mostly for renaming things in code, spreadsheet headers and file names.
Drawing from it. Paste a list and let something pick: a single name, a wheel to spin on screen, or a split into balanced teams.
How these tools read your list
The drawing tools all share one behaviour that catches people out, so it is worth stating once here rather than rediscovering it on each of them.
Lines win over commas. If your text has more than one line, every line is
one entry and commas inside it are just punctuation — so Smith, John on its own
line is one person, not two. Commas only separate entries when the whole list
sits on a single line. That rule means a list of names in Surname, Firstname
form pastes in correctly without any cleanup, which is the case that would
otherwise break most often.
Pasting a spreadsheet column works. Copying a column out of Excel, Sheets or Numbers produces one value per line, so it pastes in correctly with no cleanup. Copying a row does not.
Blank lines and stray spaces are ignored. Trailing whitespace is trimmed, empty lines are dropped, so a list pasted from an email does not need tidying first.
Repeating an entry weights it. None of them has a weight field. If someone should have three times the chance, put them in three times — the draw is uniform over lines, so duplicating a line triples its odds. The same trick works on the wheel, where it also shows up visually as three slices.
Where the rest of the text tools are
Text that needs encoding rather than counting or reshaping is under Converters — Base64, binary, and number systems. Anything involving randomness in a form you may need to prove was fair is under Randomizers, including a verifier for draws.
