What repetitive data tasks are you still doing manually?

Lately I've been working a lot with CSV files from different sources (banks, exports, random tools), and I keep running into the same issue:

- inconsistent column names

- messy date formats

- duplicate / empty rows

I end up fixing things manually more often than I’d like, even though I know it should be automatable.

I’ve tried Power Query and some scripts, but it still feels like there are always edge cases that break the flow.

Curious — what’s a repetitive data task you still do manually even though you know it shouldn’t be?
