MDB ACCDB Converter

About This Tool

MDB ACCDB Converter offers a straightforward path from legacy Access databases to modern data targets. It accepts MDB or ACCDB files and exports data into CSV, XLSX, SQL, or JSON formats, enabling integration with analytics, reporting, and enterprise data stacks. The tool is designed for developers, data engineers, and IT admins who need dependable, script-free exports for migration or archival projects. Example: exporting customers and orders to SQL inserts for a data warehouse, exporting product catalogs to CSV for BI dashboards. It supports single-file and batch workflows, with per-file options and clear output naming.
Conceptually, the tool reads the Access schema (tables, columns, data types, primary keys, and relationships) and applies deterministic mappings to the target format; it reconstructs table schemas when requested and writes data row by row to the selected format. Required features include file upload, input validation, format selection, and reliable data export. Optional/advanced features include batch processing, schema export as separate metadata files, per-table filtering, and configurable null handling.
Inputs include input_file (file, .mdb/.accdb, required) and output_format (CSV, XLSX, SQL, JSON, required), with optional flags include export_schema, max_rows, and include_nulls. Outputs are generated files with per-file metadata: filename, format, row_count, column_count; outputs can include separate schema files when requested. Algorithms & Calculations: Data-type mapping rules translate Access types to target equivalents; SQL generation uses standard CREATE TABLE and INSERT statements; JSON/CSV/XLSX writers implement consistent row handling. Error & Edge Cases: Handles missing inputs, invalid file formats, or unsupported data types with warnings and partial exports when safe; password-protected or corrupted files are rejected. Industry/Region & Localization: Date/time values use ISO 8601 in CSV/JSON; numbers use locale-neutral formatting; outputs follow common SQL and spreadsheet conventions. Assumptions & Exclusions: Assumes unlocked Access files; does not execute embedded queries; does not provide UI styling; does not perform in-place database edits; no support for encrypted databases.
