However, the buffer is not unlimited in size and if the spreadsheet file is left open 
indefinitely, the buffer could overflow causing loss of data. It is therefore good 
practice to close the spreadsheet file immediately after use. 
 
Another item to keep in mind regarding the spreadsheet files is that these files will 
open directly in Excel. However while closing the file, Excel will put up a dialog 
box stating that the open file was created in an earlier version of Excel and ask if 
the user wishes to update it to the latest version of Excel. Always pick NO. This is 
because the spreadsheet object in Lookout is not capable of writing to a file later 
than Excel 4. If the user needs to use the file in a later version of Excel, it is 
recommended that a copy of .csv file be made for use in the newer version, 
leaving the original for Lookout to log data. 
 
4.4.2 Converting CSV Files to ACCESS Database Files 
It is easy to convert the .csv data files to a Microsoft® ACCESS database file. To 
do so create a new database in Access. Then create a new table to import data 
from external files. Navigate to the location of the .csv file and click on Import. 
Follow the instructions to complete the Access table created from the .csv file.
