Load five messy CSV files into clean ClickHouse tables. Handle inconsistent dates, mixed null representations, duplicate headers, and trailing delimiters.
Thread started: 019d2cde-d1ff-74d2-a089-42b52e84562d
Turn started.
I’m loading the CSV directory and checking the file structure first so I can identify format problems before creating the ClickHouse table and import path.

I’ve confirmed the bad rows: mixed date formats, `N/A`/`null`/empty numerics, a repeated header row, and a trailing empty column in one file. Next I’m checking the ClickHouse setup and then I’ll build a normalization/import script around those specific issues.

I have five CSV files with event data in /data/csv/. They need to go into ClickHouse but I think some of the files have problems — weird dates, missing values, maybe duplicate headers. Can you get all the data into a clean table?

ClickHouse installed but not running. Five messy CSV files in /data/csv/ with inconsistent dates, mixed nulls, duplicate headers, and trailing delimiters.
Create a ClickHouse table and load all five CSV files into it, cleaning data issues along the way.
