Alfred Zolo's Free CSV Deduplicator

Alfred Zolo's Free CSV Deduplicator gives you the possibility to remove duplicate lines from CSV and TXT files. This is a simple and straightforward software application that performs tasks with minimal user assistance and doesn't require setup.

Portability advantages

As there is no setup pack involved, you can save the program files in any part of the hard disk and just click the executable to launch Alfred Zolo's Free CSV Deduplicator. Otherwise, you can keep it stored on a USB flash drive to directly run it on any PC with minimum effort. It shouldn't make any changes to your Windows registry, unlike many installers.

Load a CSV/TXT file to delete duplicate lines

It's wrapped in a user-friendly interface made from a large window split into two horizontal panes, where you can load a CSV or TXT file to view its data, as well as click a button to remove duplicates and check out results. Unfortunately, Alfred Zolo's Free CSV Deduplicator doesn't highlight differences between the original and new file, so you will have to manually inspect them.
It's possible to copy text selections to the Clipboard, as well as to save the changed information to a CSV or TXT document by just specifying the output directory and file name. There are no other notable options available here.

Evaluation and conclusion

We haven't come across any unpleasant surprises in our tests, thanks to the fact that the software utility didn't hang, crash or prompt error messages. As we expected, it carried out tasks swiftly while remaining light on system resources consumption.
To sum it up, Alfred Zolo's Free CSV Deduplicator quickly eliminates duplicate lines from CSV and TXT files, enabling you to save the new data. However, it doesn't support more advanced settings.
