Can a Macro Process a Web Page in the Background?

I have a Macro which goes to a webpage, extracts some data using javascript and sends sms to me. Is it possible to schedule it to run once a day and running in the BACKGROUND? I think it is not possible since it needs to use the browser?

I hope you don't mind that I have revised your topic title to better reflect the question you have asked.

Running macro at the background possible?

The answer is: Maybe. :wink:

The first, running once a day, is definitely possible. Use a KM Periodic trigger.

If your browser is either Safari or Chrome, and is always open, then you might try using these KM Actions:

Of course you will need to close the tab, but for now see if those Actions will work with the Browser in the background.

For now, I recommend Chrome. There seems to be a slowdown with Safari in some cases. See

Thanks Michael!
Yes that's what I did, the macro is currently working fine.
By background, what I meant is that it doesn't start a front window/tab so it won't affect whatever app running as front windows.

So does that solve your problem?
if so, please check the "Solution" checkbox at the bottom of my above post so others will know.
If not, please post your follow-up questions.

No it doesn't. When the macro runs at schedule time, it opens a Chrome window as front window.

Please upload your macro.
That is most likely because you are using an Activate App Action, which you should not do, unless the app is not running. In which case you can Activate Last App at the end of your Macro.

See How to upload your macro. Instructions for uploading to an existing post are just below the main instruction.

This is the simple macro. It open google search and extract the exchange rate. I could use your wait element macro instead of simply pause for 3 seconds :slight_smile:

get exchange rate gbp Macro (v9.2)

OK, it looks like KM always brings the Browser to the front when using any of the Browser window actions. So we will have to use AppleScript.

Here's TEST script that works fo me. It leaves Chrome in the background with a new tab as its Active Tab, ready for a JavaScript in Browser Action.
Original script was developed by Chris @ccstone.

Below is just an example written in response to your request. You will need to use as an example and/or change to meet your workflow automation needs.

Please let us know if it meets your needs.

Thanks. Tested the macro and it does start tab in the background without affecting current front app! I don't know anything about AppleScript though so need to find time to learn a little bit.

I did some research on AppleScript. Looks this solution is actually not working.
The script is opening a new tab as active tab, and then tried to restore active tab to original active tab. I've added below line:

		--- Restore Original Tab ---
		--	if (active tab index ≥ 1) then set active tab index to origTab
		set active tab index to origTab

It does restore active tab, but the subsequent action of "document.title" is running on the original active tab, not the tab just opened.

My original intention is to: open a new tab in the background (so it is doesn't affect the current active tab), and run some javascript on that new tab.

That was just and example of how to use Chrome in the Background.

Here's a more complete macro that opens a new Chrome Tab and then does a WebScrape of it -- ALL in the background:

Please let us know if this works for you.
