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 3 years ago
All of them can, you just have to write the parser yourselves. I prefer to use Ogmo. Source: over 4 years ago

If you're using tile-based maps, grab a tile level editor like Tiled or LDtk. These don't let you create graphics. You create your graphics in Photoshop / Krita / GIMP / etc. Source: about 3 years ago
