Find quick answers about supplier files, custom rules, correction reports and the interactive demo.
What supplier data formats can be validated?
The workflow supports supplier data in Excel, CSV, JSON, XML and similar structured formats.
Can I validate supplier Excel files by email?

How do custom supplier validation rules work?
You define required fields, valid formats, allowed values and the severity of each issue. The same rules can then be reused for every supplier submission.
