FAQ

How do I get comma + space?

Enter ", " (comma then space) in the Delimiter field to match the common CSV-style format.

Can I use a pipe or semicolon instead of a comma?

Yes. Type any character or short string into the delimiter field — pipes and semicolons are common alternatives for SQL and data imports.

Does it trim extra spaces from each line?

Leading and trailing whitespace on each line is trimmed so your joined output stays clean.
