[support] Drupal7 Import excel sheet into database

[Iain William Wiseman]

Hi Everyone,

Firstly hope I have the right forum.

I have a excel spreadsheet each month which contains membership data. I 
want to upload this to a table which I have created in my module.

I have googled a bit to try and understand the best way to do this but 
am still unclear.

Ideally I would like to provide a screen with
Year
Month
File path
Browse Button

(Which I have done)

How do I get the data from the excel and into the table? As I say this 
will be done once a month and will probably want to rollback.

Thanks,
Iain
