Hello Firdaus,
The easiest solution is to convert the SAC data to simple ASCII format and “import” the text values into Excel.
One possibility is to use the ‘sac’ program to write the data in “SAC alphanumeric” format, which is just ASCII. The challenge is that this data is not easily imported into Excel due to how it is formatted (the series spans multiple columns).
An easier possibility is to use one of many programs to convert the SAC data to simple ASCII in a single column of data (and time stamps).
If you can compile software from source code, one such program that I would recommended is called "sacdump” available here:
https://seiscode.iris.washington.edu/projects/sacdump
To print all the defined headers and the all the samples, you can use a command line like this:
$ sacdump -a -D mydata.sac > mydata.txt
That command would save the output to a file mydata.txt, which can then be easily imported into Excel.
The man page (and Wiki) contains full usage:

If you cannot compile software you should let the list know what system you are running on for other suggestions.
regards,
Chad
