SLD to STEP

Hi guys i'm hoping for some help converting my SLD files to STEP files (Solidworks 2018-2019)

I'm doing a degree top up course along side a full time job and my uni is 60 miles away, I am unable to download any software on my laptop as it is a work laptop therefore, i don't have admin rights.

I was wondering if anyone would be able to convert my files for me.

Would be a big help.

Kind regards.
