@v9um It’s ok if you don’t get something right away… it’s called learning 
The thing is, you are already working with an array. You are properly testing values (such as condition SaveLoadArrayPos[0] = “ColorBlock”) as well as transferring them to an object (set Laps of Blocks = SaveLoadArrayPos[2]).
So, to save your data, you can just do the opposite - write the values into the array. It will be a two-dimensional array, so for example the first property of the first block will be at Array[0][0]. The second property will be Array[0][1]. The second block will be Array[1][0], Array[1][1], and so on.
You don’t need to convert any of this to a string until player hits the share button. When they do, you can either use your method to encode it, or just use the expression ToJSON(Array) which returns a JSON string containing the array data.
