The Problem with Today's Data Tools

Existing solutions put your data at risk or require manual, error-prone work.

Privacy Risks

Online data cleaners require uploading your sensitive files to their servers, where your data can be stolen or leaked.

Excel Hell

VLOOKUP fails on slight spelling variations. "Jon Smith" and "John Smith" are completely different to Excel.

Duplicate Dilemma

Identifying 'Ahmad' and 'Ahmed' as the same person is impossible in Excel without complex scripts.

The DataFrog Solution

Powerful data cleaning with AI, entirely on your computer.

AI Fuzzy Merge

Join two files even if names aren't spelled perfectly. It's like VLOOKUP with a brain.

  • Smart name matching (Jon → John)
  • Merge Lists Offline

Privacy Mode

Anonymize PII (emails, phones) instantly before sharing files. Keep sensitive data secure.

  • Mask Emails (j***@gmail.com)
  • Mask Phone Numbers

Smart Repair

Automatically fixes broken CSV rows (like '$3,500' split by commas) that crash other tools.

  • Fix Malformed CSVs
  • Standardize Dates
