About This Tool

The MDB Viewer Online tool reads Microsoft Access database files (.mdb/.accdb) and presents their schema and contents in a browser-based view. It parses the file's metadata to enumerate tables, columns, data types, and relationships, then renders a readable, non-destructive representation of the data. Conceptually, it treats the Access file as a portable data catalog, enabling quick understanding of structure without requiring a local database instance. Primary users are developers, data analysts, and IT staff who need to assess data sources during migration, auditing, or integration projects. Unique value lies in in-browser parsing, immediate schema discovery, and one-click export to CSV or JSON for offline analysis. Core features include: file-based input, schema extraction, table-level previews, optional row sampling, and export options. Use cases include validating table definitions before ETL, inspecting legacy databases, and generating documentation of data assets.
