Hi Chris,

Yes, Excel can definitely help you with this task. Here's how you can convert KB to MB and GB and then sum them up in GB:

1. First, create a new column in Excel where you will enter the file sizes in KB.
   
2. Next, create two new columns for MB and GB. In the MB column, enter the formula
   Formula:

   "=A1/1024" 

   (assuming your KB values are in column A). This will convert the KB values to MB. In the GB column, enter the formula
   Formula:

   "=B1/1024" 

   (assuming your MB values are in column B). This will convert the MB values to GB.
   
3. Now, you can sum up the GB column to get the total amount of disk space saved. To do this, simply use the SUM function and select the range of cells in the GB column that you want to add up. The result will be in GB.
   

For example, if your KB values are in column A and you have converted them to GB in column C, you can use the formula to add up the total amount of disk space saved in GB.
