The Document to Database ERD utility extracts database tables, entity attributes, primary/foreign keys, and relational cardinalities from raw SQL schemas or Markdown tables into visual Entity-Relationship Diagrams (ERDs).

By executing schema parsing and Mermaid entity rendering locally in your browser, your proprietary database architectures, table names, and schema relationships remain strictly confidential with zero cloud exposure.
