I am using Office 365 and I have an Excel file with multiple tabs.
I need to securely store the Excel spreadsheet in Sharepoint with no access to most people.
Various departments are allowed to view a specific tab each only.
To my knowledge this can be done via the Excel webpart, which could then be placed on each department's subsite, which than links to the specific tab of the Excel file.
I am looking for someone who could configure this for me on my test site collection and give detailed information on how to make it work as required.
Please quote the code work "EWP" at the beginning of your bid, so that I know that you have read the requirements.
