MS Access to OpenOffice Base: Easy Table Converter Software

MS Access to OpenOffice Base: Easy Table Converter Software

What it does

• Converts MS Access (.mdb, .accdb) tables to OpenOffice Base compatible format.
• Preserves table structure: field names, data types, primary keys, indexes.
• Transfers data values with proper handling of NULLs, dates, and numeric formats.
• Supports single-table and batch conversions for multiple databases.

Key features

• Format support: Reads Access 2000–2019 (.mdb, .accdb) and writes files usable by OpenOffice Base (HSQLDB, Firebird embedded, or ODBC connection).
• Data type mapping: Automatic mapping of Access types (Text, Memo, Number, Date/Time, Currency, Yes/No, OLE Object) to the closest Base equivalents; configurable overrides for specific fields.
• Primary keys & indexes: Recreates primary keys and non-clustered indexes where supported by the chosen Base backend.
• Batch mode: Convert many tables or whole Access databases in one run.
• Preview & validation: Preview mappings before conversion and run post-conversion validation reports (row counts, checksum comparisons).
• Error handling & logging: Detailed logs for failed rows, skipped fields, and conversion warnings.
• Unicode & locale support: Handles multi-byte characters and allows locale-aware date/number formatting.
• Command-line and GUI: Graphical wizard for one-off users and command-line interface for scripted or automated workflows.
• Performance options: Chunked transfers, transaction batching, and optional parallelism for large datasets.

Typical workflow

1. Select Access file(s) (.mdb/.accdb).
2. Choose target OpenOffice Base backend (HSQLDB, Firebird embedded, or connect to an external DB via ODBC/JDBC).
3. Configure table and field mappings (accept defaults or customize).
4. Run preview and validation.
5. Execute conversion; review logs and validation report.

Limitations & considerations

• Complex Access features (queries with VBA, forms, macros, OLE objects) are not converted—only table schemas and data.
• Some Access-specific data types or constraints may require manual adjustment post-conversion.
• Large attachments or OLE blobs may need external extraction and re-linking.
• If target Base uses an embedded engine (HSQLDB/Firebird), check engine-specific limits (column name lengths, reserved words).

When to use

• Migrating legacy Access tables to an open-source desktop database.
• Preparing data for cross-platform sharing with LibreOffice/OpenOffice users.
• Consolidating Access data into a DB backend accessible via ODBC/JDBC.

Quick tips

• Back up original Access files before conversion.
• Run conversions on a copy when testing mapping options.
• Use CSV export as a fallback for problematic tables.
• After conversion, open the Base file and test key queries and reports to confirm integrity.
