What are these tools for?
Most records that move between sales tools, enrichment platforms, and CRMs arrive with at least one data-quality problem - duplicate contacts, missing fields, invalid email addresses, inconsistent company names, or company records that have not been checked against public register data. 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 or pre-enrichment check. They tell you what needs fixing before the record becomes operational. They do not store your data or modify your files. For the full cleaning workflow - deduplication, field standardisation, email validation, and a clean export - see the DataFixr CSV cleaning tool.
