it won't be the original readable code but you can use decodeFunction and string.dump it and then save the string and then read the string with a hexeditor.

You can download the unluac tool from the site "sourceforge.net/projects/unluac/" and perform the decode operation.
Code:
function createTempFunction()
    local data = UDF1.CEEdit1.Text
    local tempfunction = decodeFunction(data)
    local dumpedFunction = string.dump(tempfunction)
    local file = io.open("temp.lua", "wb")
    file:write(dumpedFunction)
    file:close()
end

function checkJar()
    local filename = "unluac.jar"
    local file, err = io.open(filename, "r")
    if file then
        file:close()
        print("unluac.jar file found.")
        return true
    else
        print("Error: " .. err)
        return false
    end
end

function UDF1_CEButton1Click(sender)
    local unluac = checkJar()
    if unluac then
        createTempFunction()
        local lfs = require("lfs")
        -- Get current working directory
        local currentDir = lfs.currentdir()

        -- Java execution command
        local command = "java -jar " .. currentDir .. "/unluac.jar " .. currentDir .. "/temp.lua > " .. currentDir .. "/dectemp.lua"

        -- Execute the command
        local result = os.execute(command)
        if result then
            print("JAR file executed successfully.")
            local command = "notepad dectemp.lua"
            os.execute(command)
        else
            print("An error occurred while executing the JAR file.")
        end
    end
end
