Product Imports — Calendar Date Check

Use this endpoint when you need to specifically validate calendar date columns in a product imports CSV before ingesting data into a product catalog or inventory system. It is purpose-built for the product imports domain with date-specific rules, category allowlists, and row-level reporting — making it more suitable than a generic CSV validator when date correctness and product category compliance are the primary concerns.

• CSV exceeds 100,000 character limit — request rejected
• CSV contains fewer than 1 row of data — validation cannot proceed
• Delimiter mismatch causes parsing errors and incorrect column detection
• Category values not in allowed_categories list trigger category validation errors
• Cell length exceeds max_cell_length setting — row may be flagged or skipped
• Date values outside minimum/maximum bounds are reported as range violations
• Malformed date strings that cannot be parsed are flagged as format errors
