HRIS imports fail because hire dates are in different formats than the system expects
Benefits enrollment has errors because birthdates aren't consistently formatted
Compliance reports break when date fields have mixed formats
Why HR Analysts choose browser-based cleaning
Annual benefits enrollment is next week and your employee export has date problems: hire dates from the old system are MM/DD/YY, birthdates are YYYY-MM-DD, and some termination dates are written as "March 15, 2024". The benefits platform rejects the file. You can't upload employee SSNs and salary data to random online tools. CSVCleaner standardizes all dates in your browser — sensitive HR data stays private.
