Customer and supplier master-data review tool
Review a customer or supplier CSV for blank preparation fields, placeholder values, whitespace, duplicate candidates and formatting issues. Nothing is uploaded or automatically changed. No signup required.
Use these seven columns, preserving identifiers as text. Tax ID and email cells may be empty; an empty tax ID creates a question to review, not a declaration that the record is invalid. Country formatting checks are not code-list validation. The first 100 issues are displayed; the CSV contains all review items.
| CSV record | Field | Review action |

What this tool does not do
It does not validate tax registrations, legal names, bank details, Peppol endpoints or country-specific PINT rules. It does not merge records or write changes to your ERP. Duplicate candidates require human verification: branches can legitimately share registration details.
All input stays in this page. Analytics events contain only the tool name and action. Do not treat a zero-issue report as compliance confirmation.
