Convert a list between line, comma and space
One page for every conversion: one-per-line to comma separated, space separated to one per line, space separated to comma separated, and the rest of the combinations. Trim, drop blanks and remove duplicates in the same pass.

The conversions, spelled out
One item per line to comma separated — how?
Paste the list and set “Output separator” to “Comma separated”. The result is a single comma separated line you can paste into a spreadsheet cell or a form field.
Space separated to one per line — how?
Paste the space separated text and leave “Auto-detect input”, or choose “Input: space separated”. Set the output to “One item per line”.
Space separated to comma separated — how?
Paste it, choose “Input: space separated” and “Output: comma separated”. Both selects are on the same panel, so it is one pass.
Will it keep my capitalisation and order?
Yes, unless you ask for sorting or duplicate removal. Parsing trims the spaces around each item and nothing else.
