The struggle with data duplicates

I recently faced a huge headache with duplicate entries in a dataset I was cleaning for a project at work. It reminded me of an old manual notetaking method I used for school. Does anyone have tips or tools they swear by to prevent these duplicates? I’m looking for something efficient because it seems like a small issue that snowballs fast.

I totally get the headache with duplicates; I’ve been there; one tool I found super helpful is OpenRefine. It’s great for cleaning messy data and it has specific functions to cluster and edit similar items, which can save a ton of time. Have you tried any specific tools yet, or are you just starting to look into them?

Have you looked into using deduplication features in Excel? I’ve found the Remove Duplicates function can save a ton of time, especially for smaller sets. Just remember that it won’t catch everything, so a backup is always a good idea.

It’s like fighting a hydra; chop off one head and two more sprout up! Consider using a combination of Excel’s remove duplicates function and a tool like DataCleaner for larger datasets — it could really streamline your process. How do you currently keep track of those entries?
