If I lose a game cartridge of a game and download the game on Nintendo e-shop, will I have the same data?

Question

I lost My alpha sapphire two months ago and I still cannot find it so I was wondering if this would work.

Answer 1

No.

The game cartridge is separate from your SD card. All data is saved on the cartridge. If you buy the e-shop version, it'll take up space on your SD card and be a completely different save file.
