Excel macro for data export

Create a macro in order to save on a DB some data by copying them from a list of multiple files on XLS format.

Please open attached file first (Productivity_Tool_v1.xls) before reading requirements:

* Multiple files list must be configurable by adding source files details (i.e. \documents\file1.xls - \documents\file2.xls) on tab SETTINGS
* Some source files are protected by password. It will be saved for access on tab SETTINGS
* Desired fields on DB are: number of worker (CID), day (Day), value (Value) and department (Department) on tab DATA
* All informations must be saved on DATA tab according to related field
* No records must be created on DB if value on source file is null
* Macro must be automatically executed during file opening
* A button to manually run the macro must be added on COCKPIT tab

How to read source files (check How_to_read_source_files.pdf):

* Values are ONLY stored on a specific tab set on SETTINGS
* Each number on column A shows CID
* Month's day is displayed on first row starting from C cell
* Value is displayed by crossing CID and month's day

Complete source files will be sent when project will be accepted.

Please check carefully all project files before asking informations and make a bid.
These are the first requirements for future engagements on my projects.
