Error Solver

How to fix: '...' is not a valid value for 'date'.

What happened?

Government portals require Week Ending dates in YYYY-MM-DD (ISO 8601) format. If your payroll exports dates as MM/DD/YYYY, DD-MM-YYYY, or any other regional format, the XSD parser rejects the entire submission. This is the #1 cause of first-submission failure.

The Zero-Tolerance Solution

XMLExpress parses over 50 date formats automatically — including MM/DD/YYYY, DD/MM/YYYY, M/D/YY, and DD-Mon-YYYY — converting every date to the required ISO 8601 format with zero manual effort.

Stop Fighting Government Portals

Contractors spend an average of 4-6 hours per week manually fixing certified payroll errors. With XMLExpress, you can eliminate this bottleneck entirely.

  • Automatic mapping for any CSV format
  • Instant validation against the latest WH-347 XSD
  • Support for LCPtracker, AASHTOWare, and more
  • Encrypted audit trail for zero-tolerance compliance
