How to Use This Tool

This tool counts the number of distinct (unique) values in each column of your CSV. All columns are included, not just numeric ones.

  1. Provide your CSV — Paste CSV text into the input area, drop a CSV file onto the File tab, or enter a URL on the URL tab.
  2. View your results — The unique value count for each column appears instantly.
  3. Copy or save — Copy the results to your clipboard (tab-separated for Excel) or save as a CSV file.

FAQ

3 questions
Does this tool upload my data?
No. It runs entirely in your browser using JavaScript. Your CSV data is never sent to a server.
Are empty cells counted as a unique value?
No. Empty cells are excluded from the unique value count.
Is the count case-sensitive?
Yes. 'Apple' and 'apple' are counted as two distinct values.
