Save .html in SDCARD to open later on PC

Good afternoon!

I have no experience with Arduino, I would like suggestions to simply save an .html file in SDCARD to open later on a computer. I'm not going to use an Ethernet Shield, I just want to save sensor data to a .html file so I can see it when I need it. Thank you!

First of all, thank you for the answer. Sorry for the ignorance, but in this application, this data will be visualized by lay people and so I would like to display in an already formatted and colored .html file, which can be viewed through any browser. Thank you!
