Every scan produces a detailed report. Most issues are auto-fixed.
Updates DAO 3.6 and ADODB 2.5 references to modern versions. Adds missing PtrSafe keywords to Win32 API declarations. Replaces deprecated APIs like FileSearch, Assistant, and CommandBars with working alternatives.
Converts .mdb to .accdb format. Updates Jet OLEDB 4.0 provider references to ACE 12.0. Fixes linked tables, form controls, and generates SQL Server migration scripts if you're ready to move off Access entirely.
Maps 24 legacy ActiveX controls to modern replacements. Calendar Controls, PivotTables, Data Access Pages, and other controls that Windows 11 no longer supports are flagged with specific replacement instructions.
Detects and converts 18 Jet SQL patterns to T-SQL equivalents. IIf, Nz, DLookup, date literals, string concatenation, and more — all mapped to standards-compliant SQL for SQL Server migration.

Windows 11 dropped support for several legacy components that older Access databases depend on, including the Jet 4.0 OLEDB provider, certain ActiveX controls (like Calendar Control), and 32-bit Data Access Pages. LegacyLeaps detects all of these issues and either auto-fixes them or provides step-by-step repair instructions.
Yes. LegacyLeaps converts .mdb to .accdb while preserving all tables, queries, forms, reports, and VBA code. It also generates a detailed compatibility report flagging anything that needs manual attention, and provides auto-fix scripts for common issues like Jet-to-ACE provider updates.
Absolutely. For self-service migrations, your files never leave your computer — everything runs locally. For our done-for-you service, all file transfers use 256-bit TLS encryption, we retain zero data after delivery, and all uploaded files are permanently deleted once your migrated files are returned.
Windows 11 with 64-bit Office requires PtrSafe declarations on all Win32 API calls in VBA. LegacyLeaps is an xls to xlsx converter that automatically scans your Excel files, identifies all API declarations missing PtrSafe, inserts the keyword, updates deprecated API references, and converts your .xls to .xlsx or .xlsm. Most files are fixed in under a minute.
PtrSafe is a VBA keyword required for Declare statements (Win32 API calls) in 64-bit Microsoft Office. Without it, macros that worked in 32-bit Office throw compile errors in 64-bit Office on Windows 11. LegacyLeaps automatically adds PtrSafe to all API declarations during conversion, along with updating pointer types from Long to LongPtr where needed.
Yes. LegacyLeaps supports batch conversion — point it at a folder containing hundreds or thousands of .xls files and it converts all of them to .xlsx (or .xlsm for macro-enabled files). Bulk packs of 10, 25, or 50 tokens offer volume discounts up to 47% off. There is no per-batch file limit.
64-bit Office requires three key changes to legacy VBA code: adding PtrSafe to all Declare statements, changing Long pointer types to LongPtr, and replacing deprecated APIs like FileSearch and CommandBars. LegacyLeaps handles all three automatically during conversion, plus updates DAO 3.6 and ADODB 2.5 references to modern versions.
