Redirect output from terminal to libreoffice excel file

I am running a code on a particular core and am monitoring the cache misses in that particular core every second when my code is running. I can redirect that output to a .txt file. I wanted to know if it is possible to redirect the output to a libreoffice excel file which will allow me to generate a graph easily.

Answer

You should output the data into csv or tsv formatted file.

Any spreadsheet software will be able to open that as long as you have the format correct.
