CSV Cleaner

Clean messy CSVs by trimming noise and normalizing structure.

Input

Upload a CSV, standardize the structure, fill missing values, and download the cleaned file.

  • Normalize columns when the source has inconsistent headers.
  • Use outlier removal only when extreme numeric values are clearly noise.
  • The output stays as CSV so it can drop into the next step easily.
