No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MDB opens in a few Microsoft-centric tools and is a legacy format. XLSX opens straight into Excel with columns and data types intact. MDB is at home in legacy Access databases; XLSX is the usual choice for spreadsheets with formulas, formatting and several sheets.
Every table is read. Queries, forms, reports and macros are not converted, only the data in the tables.
MDB is the format of Microsoft Access up to Access 2003, built on the Jet database engine. It holds tables, queries, forms and reports in one file. Newer versions of Access use ACCDB, and MDB is mostly opened for migration.
