If the log files are auto growing then you can find that information using the default trace after the action is completed.

DECLARE @filename VARCHAR(255) 
SELECT @FileName = SUBSTRING(path, 0, LEN(path)-CHARINDEX('\', REVERSE(path))+1) + '\Log.trc'  
FROM sys.traces   
WHERE is_default = 1;  

--Check if the data and log files auto-growed. Look for tempdb, log files etc.
SELECT 
    gt.ServerName
    , gt.DatabaseName
    , gt.TextData
    , gt.StartTime
    , gt.Success
    , gt.HostName
    , gt.NTUserName
    , gt.NTDomainName
    , gt.ApplicationName
    , gt.LoginName
FROM [fn_trace_gettable](@filename, DEFAULT) gt 
JOIN sys.trace_events te ON gt.EventClass = te.trace_event_id 
WHERE EventClass in ( 92, 93 ) --'Data File Auto Grow', 'Log File Auto Grow'
ORDER BY StartTime;

I think you are looking at this from the wrong point of view. You don't want SQL to upate your spreadsheet, you want your spreadsheet to connect to your database and get the latest data.

Create a local DSN -- using "setup data sources (ODBC) -- then connect to that data source from excel.
