If you don't have backups, I don't know a way of getting that data back.

Maybe you can recover some of your data via the .xlk files.

Hi,

I encounter a problems with all my excel files that suddently changed to 1k
in size and the content in it also change to unrecognized wordings.

Please advise what could have caused this and how can I revived back all
my excel files. I have checked on the *.xlk files are OK. Only *.xls
affected.
