Sikuli: How to click on each excel cells specific interval of time?

I am new to Sikuli. I need to click on each excel cell - one by one of the specific interval of time so how can I iterate among the excel cells.

Update 1: When mouse click on the 1st cell of a hyperlink(i.e. google.com) and specific interval of time again mouse click on the 2nd cell of the hyper link(i.e. gmail.com) and so on till the end of the cell.

Update 2: Actually, I have an excel file - In the file, specific Single column - I want to click on all hyperlink continuously using Sikuli? My question not about time interval but my question is how to click on all hyperlink one by one.

You need to do a few steps.

First locate the image of the 'A' field.
Then define that region below it.

To find an image you could use:

imageA = ("A.png")
columnA = find(imageA).below()

You also have .left() for example.

If you use .hightlight(5) you can see what region Sikuli takes.
But only use that to debug, I had problems with clicking on a field after using that in the code.

You can do 2 things then.
1. Define the region for image of number 1 but then with a left, and where they match you click.
2) Now you know the region where column A starts you could click below it every x pixels.

But I suggest option 1.
