You have a list with one item per line and you need it as a single separated line, the kind you paste into a field or a query.
This tool joins the lines for you and lets you pick the separator, so the same list can become comma, semicolon, pipe or space delimited.
How to use Comma Separator
- Paste your list, one item per line, into the left panel.
- Choose a separator from the preset menu and leave Trim on to drop stray spaces.
- Copy the separated line from the right panel.
What you can do with it
- Build a quick comma list for a form field.
- Make a space or pipe separated line for a config value.
- Turn a column of labels into one line of keywords.
Good to know
A separator tool is a list joiner, not a full CSV parser, so it does not add quotes around items by default. If an item itself contains the separator, consider a dedicated CSV tool instead.
Frequently asked questions
Does it add a space after each comma?
Yes, the comma preset uses a comma and a space so the line reads cleanly. Other presets follow their usual spacing.
What does Trim do?
Trim removes leading and trailing spaces from each item before joining, so a tidy line comes out even from messy input.
Are blank lines included?
No. Empty lines are dropped so you do not get stray separators in the result.
