It looks like this Fancy Sheet editor is causing the problems when it exports - there's a line break and some unescaped quotation marks that are breaking the JSON. This is the problem part: "Ability2": { "Name": "Decoy", "Freq": "Daily - Free Action", "Info": "The user uses the Move " Follow Me " as if it was on their Move List, and their Evasion is raised by +2 until the end of their next turn." }, the export process isn't dealing with the quotation marks as it should. "The user uses the move "Follow Me" as if it were.... needs to have that line-break removed, and the double quotation marks need to either be replaced with singles 'Follow Me', or escaped, \"Follow Me\" First thing to try (if you're able to) is to delete ability 2, and try the export/import process again to see if it's the only problem. Alternatively, replace the relevant text with this: "Ability2": { "Name": "Decoy", "Freq": "Daily - Free Action", "Info": "The user uses the Move 'Follow Me' as if it was on their Move List, and their Evasion is raised by +2 until the end of their next turn." }, If it works, you're going to have to either export your JSON in a better way (if that's possible) or manually remove any quotation marks from input fields before exporting.
