Use JSONEncode from HttpService to convert the dictionary into a string to save it, and use JSONDecode to convert the string into a dictionary.

Values of type Color3 and Instance can’t be saved in a datastore, you need to figure out how to convert them to a string value and decode them back when you load them. For both of them, as long as you don’t care about the amount of stored information, you can simply use tostring to convert them to strings. Then to decode the color you can use the following function:

local function strToC3(str: string): Color3
	local r, g, b = str:split(", ")
	return Color3.new(r, g, b)
end

Decoding the Instance/Tool may be a bit trickier, so I suggest you figure out a way to keep minimal information instead of the entire path, so if for example, the path changes later on it won’t affect old player data(for example you can store the tool name, if all tool names are unique).

Im still confused on how to implement this…
