Yes it can be opened with excel or any other spread sheet , and you can resave it. But that doesnt change the real format of the text file inside it .
It doesn't make the file parseable by the Kaspersky software.
So why do they even give the feature of clear text exports.
I even tried all scripts available on GitHub , which you should always check the whole code because it can be malicious. But even those converter scrips dont work either.
Thanks.
