This is an invaluable tool for building new flows. I use AI to assist with writing the JSON and paste directly into this tool. You may still need to create some of the actions manually to get some of the connection info for AI to write the JSON but once you've done that, it's a simple copy and paste job. To use it, open the flow and click the extension button on your toolbar and a new window will open (you sometimes need to be in the old version of Power Automate to get it to open). Update the json and click save. Go back to the flow and then back to the main page and the flow will be updated when you go back in.
This has already saved a bunch of time for our team when we had to recreate a flow in an unmanaged solution that had been deleted. We still had the managed version in another environment, so we used this extension to copy it and paste it right into the unmanaged version.
This extension is fantastic. Combined with AI, it has sped up my Power Automate development by at least 10x. There is a bit of a learning curve at first, and the error handling and logging could be improved. But once you understand how the extension works, development becomes much smoother. I’d give it 10 stars if I could.
Just installed it, running PA on browser. Had the same problems as people reported before: Clicking the Tools Extension during a flow edit only opened a short Extension setup menue. Now I found out that by switching to the "Old Designer" (or classic designer maybe in English) gets around this issue. In "Classic Designer" version of PA, clicking the PA Tools Extension indeed opens the whole code for hacking around.
Does not actually work. Clicking the extension does nothing.
This no longer works with either Power Automate v2 nor v3
Not working.
found it really useful to update a massive apply to each statement, just make sure you are in Classic mode, otherwise the button does nothing.
As of writing clicking the extension icon with the new designer ("v3") does nothing, and even with the old designer it's hit-and-miss.
Incredibly useful, thanks
