Change List Separator

What Is a List Separator Changer?

The Change List Separator tool lets you quickly replace the delimiter between items in a list. Whether you have a comma-separated list and need it as a line-by-line column, or you want to switch between different formatting styles, this tool handles it in real time.

Specify your current input separator (the character or pattern that divides your items), then choose a new output separator. Additional options let you trim whitespace from each item and remove any empty entries.

How to Change a List Separator

1. Paste or type your list into the Input List text area.
2. Enter the current separator in the Input Separator field (e.g., , for a comma followed by a space).
3. Switch to Regular Expression mode if your separator is a pattern rather than a fixed string.
4. Set the Output Separator to whatever you need — a newline, a pipe |, a semicolon, etc.
5. Toggle Trim items and Remove empty items as needed.
6. The transformed list appears instantly in the Output List area.

Common Use Cases

• Convert CSV data to a line-per-item format for easier reading.
• Reformat a bullet-style list into a comma-separated string for use in a spreadsheet or database query.
• Clean up messy data where items are separated by inconsistent whitespace or punctuation.
• Prepare data for import by switching between pipe-delimited, tab-delimited, or comma-delimited formats.
