Hi,
As far as I know, most of the macros might work well between 32bit and 64bit Excel. But there are some limitations for Excel 64bit:
Solutions using ActiveX controls library, ComCtl controls won’t work.
Third-party ActiveX controls and add-ins won’t work.
Visual Basic for Applications (VBA) that contain Declare statements won’t work in the 64-bit version of Office without being updated.
  Compiled Access databases, like .MDE and .ACCDE files, won’t work unless they’re specifically written for the 64-bit version of Office.

If you have any further question about macros, I recommend you post the question to the MSDN forum for Excel
