Is there an easier way to dump a table?

I have a table in a data store which has a table inside of it. When I tried accessing that table or printing it, it just gave a hexadecimal output. Looping through the table did not work for me either. So after some research and questioning I implemented these two functions to get the data:

	local function dumpTable(tableToDump)
	
		local tbl = {}
		
		if type(tableToDump) == "table" then
		
			for i,v in pairs(tableToDump) do
				
				wait()
	
				table.insert(tbl, tostring(v))
	
			end
	
			return "{" .. table.concat(tbl, ", ") .. "}"
			
		else
		
			return nil
			
		end
	end
	
	local function changeStringToTable(tbl)
		
		local finishedTable = {}	
		
		for int in string.gmatch(tbl, "%d+") do
			
			table.insert(finishedTable, tonumber(int))
			
		end
	
		return finishedTable	
		
	end

Is there an easier/more effective way of going about this? Thanks!

Roblox has in-built functions to convert tables to string values and vice versa.

JSONEncode and JSONDecode in HttpService

Here's some code from the wiki on how to encode a json string. It's very simple:

local HttpService = game:GetService("HttpService")
 
local tab = {
	-- Remember: these lines are equivalent
	["message"] = "succes";
	message = "success";
	
	info = {
		points = 120,
		isLeader = true,
		user = {
			id = 12345,
			name = "JohnDoe"
		},
		past_scores = {50, 42, 95},
		best_friend = nil
	}
}
 
-- A cyclic relationship like this...
tab.tab = tab
-- ...will be replaced with the string:
-- '* certain entries belong to the same table '*
 
local json = HttpService:JSONEncode(tab)
print(json)
