Find all the positions containing "text" in text?

[Jakub_Lajsek]

I basically need to know where are the positions of specific text in a text.
I made my own code that works but it’s super slow and i need to work with json files that are more than 250kb in size.

i would love to be able to use Starts At block but i didn’t find any way to make it working
I know how could it be done.
search for the “text” in text and store that pos into variable, then search for another one by setting
the starting pos to variable+lenght of “text” (to skip the first result) but when im trying to make loop until there are all, it doesn’t work…

can you please help me?
Thank you.
PS: I couldn’t find any solution on any of the forums. not even app inventor etc. that’s why I’m asking.

scene.json.txt (258.8 KB)

Do as @Douglas_Maueski said. I think the app is taking time because of the length of JSON file. It is too big to be fetched instantly.
