Sending Data from SD card to a Google Spreadsheet using ESP8266

Hello,

I need a guidance regarding on the problem that I am facing now. I'm having a problem to send three data to Google Spreadsheet which is timestamp, distance and also speed. Until now, I have managed to do the data transmission for timestamp only.

My plan is to store these 3 data into SD card. Like for example, inside the memory card it will display like this :

15:20:33 <-- time
25.2 <-- distance
13.4 <-- speed

So now what I want to do is to read these data inside the SD card and send them to the Google Spreadsheet. I have a thought to send the data by making an array to read the data easier and send them. But I have no idea how to do that. I will include my full coding as well.

Your guidance is much appreciated. Thank you.

The " <-- " is just for example it will not be in the SD card. Apology
