I have also seen Aseprite being recommended. It looks nice and I'm sure it works well, but it is not open source unfortunately. There is an open source alternative called LibreSprite, which seems to mimic Aseprite quite closely. Source: over 2 years ago
Maybe you could use something like Tiled (https://www.mapeditor.org/) or Ogmo (https://ogmo-editor-3.github.io/). They're meant to be level editors but you can also define custom metadata for tiles. And if these tools aren't suitable I would probably write my own simple editor. Source: over 2 years ago
All of them can, you just have to write the parser yourselves. I prefer to use Ogmo. Source: about 3 years ago
