LIST TRANSFORMATION TOOL

Combine multiple lines with a custom separator.

Turn a one-item-per-line list into a comma-separated string, pipe-delimited value, sentence or custom format.

LOCAL BROWSER TOOL

Run the tool

Paste one item per line, choose a separator and join the non-empty values.

HOW IT WORKS

A separator controls how line-oriented data becomes inline text.

Every non-empty line is trimmed and combined in its original order. For commas inside values or spreadsheet imports, use a structured CSV tool instead.

Your data stays local

The transformation runs in this browser tab. ClearText Tools does not upload the input to a processing server.

Review the output

Copy the result only after checking structure, edge cases and any values that affect production systems.

Known boundaries

  • Empty lines are ignored
  • Items are trimmed before joining
  • Choose CSV conversion when values need quoting

NEXT TASK

Continue this workflow

Use a related tool or guide when the result needs another cleanup, validation or conversion step.

Common questions

Is my input uploaded?

No. This tool processes the input locally in your browser.

Can I use the result without checking it?

Use it as a fast transformation, then validate important output against the requirements of the destination system.
