What is List Cleaner?

The List Cleaner is a powerful text utility that processes line-separated lists to remove duplicates, sort items, and clean up formatting. Whether you're working with email lists, product names, URLs, or any other line-separated data, this tool helps you quickly organize and deduplicate your content. It's particularly useful for data cleaning tasks, preparing import files, and managing lists of any kind.

How to Use

  2. Select the cleaning options you need (remove duplicates, sort, etc.)
  3. Optionally add a prefix or suffix to each line
  4. Click 'Clean List' to process and view the results

Common Use Cases

  • Deduplicating email lists before sending campaigns

  • Preparing bulk import files for databases
  • Formatting lists for documentation or reports

Frequently Asked Questions

Simply paste your list with each item on a new line. The tool automatically treats each line as a separate list item. You can also paste comma-separated values and the tool will process them.
When case-sensitive is enabled, 'Apple' and 'apple' are treated as different items. When disabled, they're considered duplicates and only one will remain. Choose based on whether capitalization matters in your data.
Yes! Use the prefix and suffix fields to add text to every item. For example, add a bullet point prefix (• ) or a comma suffix to format your list for different contexts.
You can sort alphabetically (A-Z), reverse alphabetically (Z-A), or keep the original order. Sorting respects the case-sensitivity setting, so uppercase and lowercase letters may sort differently based on your choice.
The 'Remove numbers only' option removes lines that contain only numbers (like '123'). Lines with mixed text and numbers (like 'Item 1') are preserved. This is useful for cleaning data exports that include row numbers.
