  • Strip blank lines or extra spaces.
  • Wrap the entire result with a prefix/suffix.
  • Control formatting for scripting, JSON prep, or command-line batching.

Everything processes instantly, right in your browser. No data leaves your device.

Example:

Input:

apple
banana

cherry

Options:

  • Separator: ,
  • Trim whitespace: enabled
  • Ignore empty lines: enabled
  • Prefix: [
  • Suffix: ]

Output:

[apple, banana, cherry]

Common Use Cases:

The Join Text Tool helps you quickly combine multiple lines of text into a single string with custom separators, prefixes, and suffixes. It’s ideal for formatting CSV or TSV data, preparing lists for database imports, generating bulk tags or keywords, merging user inputs for forms, combining text for API calls, and creating compact text blocks for publishing or programming.

Useful Tools & Suggestions:

If you’re joining text lines together, Unwrap Text Lines is a handy one to use beforehand it removes hard line breaks so everything flows naturally when combined. You might also want to try Add a Suffix to Text Lines if you’re merging lines but still want to tag or separate them in a custom way.
