NAME

       extract_vba - A utility to extract a VBA project from an Excel 2007+ xlsm file.

DESCRIPTION

       This utility is used  to extract the VBA project binary from an Excel 2007+ xlsm file. The
       VBA project can then be added to an Excel::Writer::XLSX file to enable it to have macros.

       An "xlsm" file is a version of an Excel "xlsx" file that contains an additional VBA
       project binary file. The "xlsm" file format is a collection of mainly XML files in a ZIP
       container.

       The extracted VBA project is an OLE Compound Document in binary format. It is named
       "vbaProject.bin" and is generally located in the "xl" directory of the "xlsm" file.

       See the "add_vba_project()" section of the  Excel::Writer::XLSX documentation for more
       details.

       Note: you can also extract the VBA project from an "xlsm" file using the standard Linux
       "unzip" command:

           unzip -j macro01.xlsm xl/vbaProject.bin

       On Windows you can use any suitable Unzip application.
