Text Joiner

The Text Joiner merges a multi-line list into one line, inserting a delimiter of your choice between the items. The delimiter defaults to a comma, but it's a free text field — use ', ' for readable lists, ' | ' for pipes, '; ' for semicolons, or any custom separator your target format needs.

It is the exact inverse of our Text Splitter: Splitter breaks one delimited string into lines, Joiner packs lines back into a delimited string. Together they let you reshape list data between the two most common formats without touching a spreadsheet or writing code.

Joining happens live as you type or change the delimiter, entirely in your browser.

The most common job is building comma-separated values for another system. A column of IDs copied from a spreadsheet arrives as one-per-line; a SQL 'IN (...)' clause, an API request, or a tag field wants them comma-separated. Paste, set the delimiter, copy — done.

Developers use it to build test data and config values: joining a list of hostnames with ',' for an environment variable, or joining keywords with ' OR ' to build a search query.

It also beats find-and-replace in a text editor, which struggles with newline characters and always seems to leave a stray delimiter at the end — the Joiner only inserts separators between items.

1. Paste your list into the input box, one item per line.

2. Type your delimiter into the 'Join Using Delimiter' field (default is a comma).

3. The joined single-line result appears instantly.

4. Copy the output to wherever it's needed.

Input:

apple banana orange

Delimiter: ', '

Output:

apple, banana, orange
