A super easy tool is OpenRefine—it’s like Excel but way better for messy dataset or data set cleanup. You can cluster similar values and clean ‘em up in batches.

Also, don’t forget to check for missing values early on. Nothing worse than realizing half your data is NA after hours of work.

Pro tip: Save a backup before you start deleting stuff. Trust me on this one.
