Delimiter converter
Turn a pasted list into a delimited string: change separators, wrap, prefix or suffix each item.
What is a delimiter converter?
A delimiter converter takes a list of text (pasted from a spreadsheet column, a CSV export, or typed one item per line) and rejoins it using a different separator. It's the fastest way to turn a newline-separated list into a comma-separated string, or the other way around, without writing a script.
Common use cases include turning a spreadsheet column into a comma-separated list for a SQL IN (...) clause, converting a CSV column into one entry per line, building a quoted list of values for code or config files, and cleaning up pasted data by trimming whitespace and removing empty lines.
