I built this originally so I could make videos on prediction markets and break down my ideas so I wanted to share it with all of you :)

Every solution failed… built-in functions returned silent NULLs, UDFs took 6 hours to run, pandas UDFs still failed on 8% of rows.

I hate using regex on emails, addresses, and emails even more. I hate that there are no data cleaning tools for pyspark so I built one.

You own the code, with no external dependencies to manage or worry about breaking changes.

Inspired by shadcn's component approach: instead of importing a black box, you get battle-tested PySpark functions that live in YOUR repository. Handle email validation, address parsing, phone formatting.
