How to convert between delimiters
The same list needs a different separator almost everywhere. Copying from a spreadsheet gives you tabs, a CSV file wants commas, a search box wants one item per line, and a log filter wants pipes. Pick the delimiter the text uses now and the one you want, and the list is rewritten. Besides the six presets you can type a custom delimiter, writing a tab as backslash t and a newline as backslash n.
Quoted values are not parsed. Proper CSV treats a comma inside double quotes as part of the value, but this tool splits on plain text, so that comma becomes a separator too. When the input contains quotes the result warns you to check the output; for data like that, opening it in a spreadsheet and moving whole columns is safer.
Repeated delimiters produce empty items. By default those are dropped and the result says how many. Spaces around each item are trimmed as well. Turn on duplicate removal to keep only the first occurrence, and the result reports how many were merged and how many remain. To go the other way and put a list on a single line, a line joiner is simpler.
Frequently asked questions
If you copied a column, set the current delimiter to newline; if you copied a row, set it to tab. Then choose comma as the new delimiter and paste the text exactly as it came.
It is treated as a delimiter and the item gets split, because the tool does not interpret CSV quoting rules. If any quotes are present, a warning appears in the result notes.
