What are these tools for?

Most CSV files that move between sales tools, enrichment platforms, and CRMs arrive with at least one data-quality problem - duplicate contacts, missing fields, invalid email addresses, or inconsistent company names. These problems are easier to catch before import than to fix inside the CRM afterwards.

The tools on this page are designed for a quick pre-import check. They analyse your CSV and tell you what needs fixing. They do not store your data or modify your file. For the full cleaning workflow - deduplication, field standardisation, email validation, and a clean export - see the DataFixr CSV cleaning tool.
