Duplicate Line Remover
Strip repeated lines from lists, exports and address dumps.
Merged mailing lists, log exports and copied spreadsheet columns are full of repeats. This tool keeps the first appearance of every line and deletes the rest, reporting how many duplicates it removed so you can sanity check the result. Options let you ignore capitalisation, ignore leading and trailing spaces, and drop empty lines, which between them catch most of the near-duplicates that simple matching would miss. The order of the surviving lines is preserved, so a list that was already sorted stays sorted. Processing is immediate and your data never leaves the browser tab.
How to use the Duplicate Line Remover
- Paste your list, one item per line.
- Tick the matching options you want applied.
- Press Remove Duplicates and copy the cleaned list.
