You're welcome. I went and tried editing a save file myself after writing that post.

works very well. It has a feature to label items for you - just start with uploading `data/Items.json` and only then upload your save file. This way all items be labeled properly and you won't have to guess anything.
Yes, using an offline save editor is even better, but I never tried it and can't say if it works and how well.
Well, you lost a save to an early demo that will most probably be useless on newer versions anyway, and got a valuable lesson out of it - always create backups before modifying files of any importance.
I usually also have a ton of save files in every game I play.
