SAR graphing/plotting into Excel

First, I'll cite my sources that helped make this easier for me:

Notes:
I've told sysstat to log the max history which is 30 days. Then, I use the following command to provide output of said disk I/O from the first day:
Code:
sar -b -f /var/log/sa/sa01
From here, I use sadf to output to Excel-friendly format:
Code:
sadf -d /var/log/sa/sa01 -- -b | sed 's/;/,/g' > storage01_diskio_1-3-17.csv
For the curious, here's what the output looks like, raw:

Code:
host1,599,2017-01-01 06:10:01 UTC,1.39,0.00,1.39,0.00,26.92

In Excel, I import the data to graph by copying/pasting the output from the previous command. From here, I click the Data ribbon and choose "Text to Columns".
From the new window that appears, I choose the "Delimited" radio button and click Next
I choose the "Comma" checkbox and click Next
"Column Data Format" should be set to General so I click Finish
I now insert a new line above it all for the following headers:
Hostname | Interval | Time | TPS | Reads/sec | Writes/sec | bread | bwrit
While still in Excel, I click the Charts ribbon, highlight all data and choose Scatter->Smooth Marked Scatter.
Lastly, I choose Layout 1 from "Chart Quick Layouts"
