Hi!
I was wondering if this was possible?
I have an image of a map from my old amiga game (16 x 16 tiles) and I have the old tileset graphics that I created a tileset in Tiled.
What I was hoping was if there’s a function to grab the map data from the image of the map using the tileset so editing could continue in tiled?
Is this at all possible?
Many thanks in advance for your time

Not in Tiled. It could be implemented via scripting, but that would be a waste of time since different tools already exist for this task, e.g. Online Tileset Extractor (this one can save the results in Tiled-compatible formats).
Note that most real maps are made with several layers and have overlapping tiles, and I’m not aware of any tool that can properly separate the overlapping areas into separate tiles. With Amiga games, this should not be an issue, I think.
Thank you Eishiya, I shall try that. It looks to do exactly what I need! 
Have a great day
For anyone here who reads this in the future I thought I would try my luck on with ChatGPT and afteer a few awkward tries it managed to do exactly what I needed (I needed the tiles to match the arrangement in a tileset image I had). I couldn’t believe it.
It even save it out as a .tmx file. I did 20 maps that way and it converted every image of the map into a .tmx file of the map for further editing/improving.
