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

What happened?

Every WeekEnding date must be in YYYY-MM-DD format. MM/DD/YYYY, DD/MM/YYYY, and other regional variants are rejected. A single row with a bad date format can delay payment on the entire project.

The Zero-Tolerance Solution

XMLExpress detects and converts 50+ date formats automatically, including MM/DD/YYYY, DD-MM-YYYY, M/D/YY, and DD-Mon-YYYY — all to the required ISO 8601 standard.
