We also have weekly summary spreadsheets, that show an extract of
certain pieces of information. However, the information is not new
each week. Last weeks spreadsheet will be copied to a new one, the
figures from last week will remain and be added to, depending on the
stats received this week, and so a new running total of stats is
received. This process is then completed again next week, and so on.

What I would like to do, is automate it, rather than having to find the
figures each week. However, figures from previous weeks have to remain
intact. By this I mean, we must be able to load any spreadsheet for a
previous week, and see what the state of play was that week. This is
where I think I would have a problem with automation. If the weekly MI
spreadsheet is automatically updated each week, loading a previous
weeks spreadsheet would overwrite the figures contained in it, with
those from the current weeks file.

Is there a way to 'lock' the figures once they have been updated, so
that further loads will not update the data?
