How to accumulate data everyday

Dear Master,

What i want is to do everyday web scrapping, takes some data from any sites and accumulate that data into a cell for example into array. However the problem is the cell have run button, so if i click it accidentally, all data accumulated on that cell will be wiped out and the array will be empty back.

Can anyone help me how to preparring cell or variable with initial value that will never reseting its value at anytime.

Thanks before

Can you include a link to a notebook with the described behavior ?

Please refer to

SomeArr always reset its value when i re-open the url…
What i want is SomeArr keep continue accumulating its content even when i leave its web page?

Is there any solution?

You can then use an external cron service to regularly “awaken” your glitch instance and have it fetch the data.

More details on persisting data with can be found here:



I will take a look at

Will persisting data to local storage help you? This notebook shows how we can add data to local storage for a cell. Note: You have to sync the localstorage and cell value though.
