Map exporting as an Lua file

I am coding my own rpg game and want to use Tiled for the maps. I got a given source code to run the maps. The maps are exported as an Lua file. This source code aspects the data sorted in a list and aspects maps from Tiled 1.1. I got version 1.4. In this version the data is stored in a single string. is there a way to export the map in a different way for lua? Or is it possible to get an older version of Tiled? I am not able to download an older version from this webside.

Thanks

You can download older versions on GitHub, but for your needs you don’t need an older version. You just need to change the Tile Layer Format in the Map Properties to CSV (if it’s currently a single string, then it’s set to one of the base64 formats):
