I recently was working on a project where my sensor data was sent to a google spreadsheet and hence was displayed on my android application.

I chose to send my sensor data to the google spreadsheet as its an easy task using a temboo.com choreo.

I was using a MSP430 Launchpad with a CC3100 Booster pack but the same choreo runs for arduino uno with a wifi shield and arduino yun.

Now as the android app cannot fetch data directly from the spreadsheet hence we got the values in the desired format.

Step 1: Make Your Google Spreadsheet Shared

In order for the spreadsheet to be accessible by the php script, you need to share the spreadsheet.

On the top right corner there is a button in blue to share the spreadsheet. Click on it and in the popup that appears click on,"get sharable link".

Step 2: Edit the URL to Get CSV Values From Google

The link in the address bar would be like this:

https://docs.google.com/spreadsheets/d/1HZzq8imLd0Rb0IKY6eUlQ3ND1_EUiPXvdjkbSfZRhLc/edit#gid=0

Where "1HZzq8imLd0Rb0IKY6eUlQ3ND1_EUiPXvdjkbSfZRhLc" is the unique sheet ID.

You have to replace the part after the unique ID with,"export?format=csv&id="

and then paste the unique ID again.

Hence the above URL becomes:

https://docs.google.com/spreadsheets/d/1HZzq8imLd0Rb0IKY6eUlQ3ND1_EUiPXvdjkbSfZRhLc/export?format=csv&id=1HZzq8imLd0Rb0IKY6eUlQ3ND1_EUiPXvdjkbSfZRhLc

Now paste the URL hence obtained in the PHP script we have created and save it.

Download it here

Now you have to upload the php file to you hosting. You can use a free hosting service for it.

Upload the php file to the root folder of the host.

Hence the values are available in CSV for whatever use you want.
