  • clean_csv

    Clean a messy CSV given as text. Fixes headers (snake_case), trims whitespace, parses mixed date formats to ISO, turns money strings (e.g. "€1.200,50") into numbers, standardizes known categories, and drops duplicate rows. Returns the cleaned CSV text and the list of steps that were applied. The cleaning transformations are done by deterministic, tested code — the values are never invented or rewritten by a language model. Args: csv_text: the raw CSV content, including the header row.
