Questions

Are my files uploaded?
No. The tool runs in your browser and your files are processed on your device. The page downloads the tool's code from public content networks, which see an ordinary web request, but your files are never sent to SkillEra.
Do I need an account?
No. These tools work without signing in. A few controls are marked Pro and unlock with a paid plan; everything else is free to use.
What does the CSV cleaner change?
Only what you choose: trimming whitespace, dropping empty rows and removing duplicate rows, on files up to 5,000 rows. Dropping columns, removing duplicates by a key column and larger files are Pro. It also profiles each column (type, missing values, unique counts) so you can see the data before you clean it.
