Worked perfectly! I found it kind of weird that dumping gave 0 (manual save), 1, 2, 3, 4 and 5 (autosaves) but they're not in order. 5 is the first autosave? Just kinda odd, I haven't done a ton of save tinkering or anything before though, so it might just be me.
Slightly off-topic, with the web-based save editor, is there a way to add gear/items you don't have into your inventory? I saw the "Add Item" button at the top, but it seemed to just kinda randomly add food items, and I didn't see anywhere to manually specify the added item.
I had the same problem with the BOTW editor when I first used it. You can change the added item type with the controls. Click on the item's icon, then pick in the dropdown list. Have fun!
