How to Convert Newline to Comma
The Convert Newline to Comma tool is the ultimate utility for transforming vertical lists into horizontal, comma-separated strings. It's designed for:
- Database Admins: Quickly generating SQL
IN (...)clauses from a list of IDs or values. - Programmers: Creating array definitions (e.g.,
["a", "b", "c"]) from raw text data. - Content Creators: formatting tag lists or keywords for upload forms that require comma delimiters.

Our tool goes beyond simple replacement with advanced formatting options:
- Custom Separators: Use commas, pipes (|), semicolons, or any other delimiter you need.
- Smart Quoting: Automatically wrap each item in single or double quotes - a lifesaver for SQL and coding.
- Clean Output: Options to trim whitespace and remove empty lines ensure your result is ready to use immediately.
