# RowGuard CSV Validation API

> Validate UTF-8 CSV data against a caller-supplied schema before importing it into a database or automation workflow.

RowGuard reports missing values, type errors, numeric bounds, allowed-value failures, duplicate identifiers, and possible spreadsheet formulas. It returns structured record and column references and can include rows that passed validation. It does not store files or call an AI model.
