How to Use:

  1. Paste your list into the Input Text box. Each item should be on its own line.
  2. Use the Options panel to adjust behavior:
    • Trim Lines: Remove leading/trailing spaces before counting.
    • Case Sensitive: Treat “apple” and “Apple” as different items.
    • Ignore Blank Lines: Skip empty lines completely.
  3. The output updates instantly on any change. Each unique item is shown alongside how many times it appeared, sorted from most to least frequent.
  4. Use the Copy button to grab the result or Export it to a .txt file.
  5. You can also Import a list from file formats like .txt, .csv, .json, etc.

You can toggle each setting live and watch the changes update immediately. The border flashes each time the output updates to signal success.

What Count List Item Occurrences can do:

Need to find duplicates in a list fast? This tool’s built for exactly that. You can take a long, messy list and see how many times each value appears in real time. It works great for tasks like:

  • Tallying names in a signup sheet
  • Summarizing logs or structured data
  • Finding duplicate keywords or tags
  • Aggregating votes or poll responses
  • Cleaning up input before importing it elsewhere

For example, if you paste:

Apple
Banana
banana
Apple
apple
unknown

And have Trim Lines ON and Case Sensitive OFF, you’ll see:

apple: 3
banana: 2
unknown

With Case Sensitive ON, the result would instead show:

Apple: 2
banana: 1
apple: 1
unknown

The tool doesn’t just count it adapts based on how strict or relaxed you want to be. Want to ignore spacing mistakes? Use “Trim.” Need precise casing control? Toggle case sensitivity. And if you’re dealing with messy input where blank lines are cluttering things up, the “Ignore Blank Lines” toggle cleans that up instantly.

It works entirely client-side, so nothing you type or upload ever leaves your browser. You can safely import lists from .txt, .csv, .md, or even .html, and the tool will treat them as plain text.

This tool is especially helpful for:

  • Writers doing content audits
  • Developers debugging log files
  • Analysts cleaning up raw exports
  • Teachers counting student responses
  • Anyone trying to spot repeats fast
