FAQ
What separators are available?
Comma, comma with a space, space, pipe, or a custom separator of your choice - useful for building CSV rows, code arrays, or delimited lists.
What does "trim whitespace and remove blank lines" do?
It strips leading/trailing spaces from each line and skips any completely empty lines before joining, so you don't end up with stray separators.
Can I use a multi-character separator?
Yes - choose "Custom" and enter any string, including multiple characters like " - " or "::".
What is this useful for?
Turning a pasted column of values (from a spreadsheet, for example) into a single comma-separated string for a query, array, or CSV row.
