How to use Change List Item Separator
- 1. Paste your list. Enter your items into the input pane using whatever delimiter currently separates them, such as newlines, commas or tabs.
- 2. Set the current separator. Enter the delimiter your list currently uses in Current separator, using \n for newline or \t for tab if the separator is not a printable character.
- 3. Set the new separator. Enter the delimiter you want in New separator, such as a comma, a pipe character, or any string you need between items in the output.
- 4. Copy the reformatted list. The output pane shows your items joined with the new separator. Copy the result into the file or system that expects that delimiter.
When to use Change List Item Separator
Change List Item Separator swaps the delimiter between items in a list for a different one. Use Change List Item Separator whenever data arrives with one delimiter but needs another for the next system in line.
- Converting a newline list to comma-separated values. A list pasted from a text editor is one item per line, but a spreadsheet formula or API call expects a comma-separated string on a single line.
- Switching a pipe-delimited export to tabs. A legacy export uses a pipe character between fields, but the tool you are importing into expects tab-separated values instead.
- Turning a comma list into newline items. A tag field exported as 'red, blue, green' needs to become three separate lines so it can be pasted into a tool that expects one item per line.
- Preparing a list for a SQL IN clause. A newline-separated list of IDs needs to become a comma-separated string to drop directly into a SQL IN clause without manually retyping the separators.
Examples

milk eggs bread

milk, eggs, bread
