Uniques
A browser-based offline "unique list" tool that takes one-item-per-line text, normalises it (case/diacritics/whitespace), removes duplicates, optionally filters and sorts by frequency, and lets you copy or download the resulting items and counts as CSV/JSON.
Instructions
- Paste your list into the “Source list” box, one item per line.
-
Adjust the options if needed:
- Ignore empty lines to skip blank lines.
- Case-insensitive to treat “Apple” and “apple” as the same item.
- Diacritic-insensitive to merge “café” and “cafe”.
- Collapse internal spaces to normalise multiple spaces inside items.
- Sorting: keep original order, sort alphabetically, or by frequency.
- Filter by count: keep only items that appear exactly, at least, or at most N times.
- Click Get uniques to generate the deduplicated list.
- Read the counters above each box to see total lines, blanks, distinct items, and how many duplicates were removed.
-
Use the buttons under each box:
- Paste to paste from clipboard into the source box.
- Clear to empty the source box.
- Copy to copy the unique output.
- Download CSV or Download JSON to export the full frequency table.
- Click Show table to display the frequency table with each item and its count; click again to hide it.
