Free Validation Utility

Migration Validation Tool

Upload source and target CSVs to reconcile your migration — record counts, field-level diffs, missing records, and integrity checks for timestamps, HTML, and attachment links. Everything runs in your browser; nothing is uploaded.

This validates a migration after the fact. Before you run one, the agent will tell you which fields are known to break on your specific platform pair — so you know what to check for here.

All parsing and comparison runs in your browser — no CSV data is uploaded. Handles quoted fields, embedded newlines, and auto-detects comma, tab, semicolon, and pipe delimiters.
