We found Access 97 MDB files in a decommissioned server backup — none of our current machines have the old Access engine installed, but this converter opened the MDB and exported every table to XLSX without errors.

A long-term client handed us their customer database in MDB format from an Access 2000 application; converting to XLSX let our team review and clean the data in Excel before importing it into the new CRM.

Legacy MDB files from a discontinued ERP held five years of transaction history — exporting them to XLSX preserved numeric precision and date formatting, which earlier manual exports had always garbled.

MDB to XLSX Converter — Frequently Asked Questions ▼

What is an MDB file?

MDB is the database format for Microsoft Access from Access 95 through Access 2003. It holds multiple tables, queries, forms, reports, and VBA code in a single Jet database engine container.

How do I convert MDB to XLSX online?

Upload your .mdb file using the button above. The converter opens the Jet database, lists the tables, and writes each one to a separate sheet inside a single XLSX workbook. Sheet names match the original Access table names.

Are all tables included in one workbook?

Yes. Every table in the MDB becomes its own sheet in the output XLSX, preserving the original column order and data types. XLSX supports up to 255 sheets, so all but the largest Access databases fit in one workbook.

Will queries, forms, and reports be exported?

No. Only data tables become sheets. Queries, forms, reports, macros, and VBA modules cannot be represented in XLSX. If you need those, keep the MDB or migrate to a SQL backend.

Can I batch-convert a folder of MDB files?

Online conversion is one file at a time. For batches, use Total CSV Converter on your desktop: TotalCSVConverter.exe C:\mdb_files C:\xlsx_out -c xlsx -log:log.txt converts every MDB into its own workbook in one run.

What is the maximum file size?

The online converter accepts MDB files up to 50 MB. For larger Access databases (Access 2003 MDB allows up to 2 GB) use the desktop version of Total CSV Converter.

Are my uploaded files kept private?

Uploaded files are deleted automatically after you download the result. They are not stored, indexed, or shared. For confidential business databases, run conversion locally with Total CSV Converter on your own machine.

What Is MDB?

MDB (Microsoft Database) is the file format for Microsoft Access from Access 95 through Access 2003. An MDB file holds multiple tables, queries, forms, reports, macros, and VBA modules in a single Jet database engine container. Access 2007 switched the default to ACCDB, but MDB databases remain in use for legacy line-of-business applications, departmental tools, and old project archives.

What Is XLSX?

XLSX is the Office Open XML spreadsheet format Microsoft introduced with Excel 2007 and standardised as ISO/IEC 29500. An XLSX workbook can hold up to 255 worksheets, each with 1,048,576 rows and 16,384 columns. XLSX opens natively in Excel 2007 and later, LibreOffice Calc, Apple Numbers, Google Sheets, and every modern programming-language spreadsheet library.
