How to Clean CSV Data Visually without Formulas

Cleaning messy data in Excel usually requires complex VLOOKUPs or specialized macros. Our visual cleaner lets you transform your data using a simple, intuitive interface.

🧹 Common Data Cleaning Tasks

  1. Deduplication: Instantly find and remove identical rows based on selected columns.
  2. Case Normalization: Fix messy casing (e.g., converting 'new york' and 'NEW YORK' all to 'New York').
  3. Masking: Protect privacy by hiding parts of email addresses or phone numbers with one click.

🛡️ Privacy First

  • 100% Client-Side: Your data is NOT uploaded to any server. All transformations happen in your browser's memory, ensuring total data privacy.
