Board Game Stats can import plays directly from BoardGameGeek. If you have another source of your plays, you can try to import a file into Board Game Stats in the sam format you can export from it.
For Android that means creating a JSON file in the structure that is exported via Settings > Export, import and backup > Export backup file… and opening that file using the Import file… option on that same screen.
For iOS you might try the steps below to import them, using Board Game Stats’ own .tsv export-format. However, that isn’t easy yet. The app just doesn’t expect anything else than its own export, so things must match quite exact.
If you’re impatient for a general import feature and determined to get it working, here are some pointers:
- The file must be tsv (tab-separated, non-quoted), just like the exported file
- The columns must match; each player has a set of five columns (since version 4: nine), so the number of columns is determined by the number of players to import
- A player’s first column title is its name, the second its BGG user id
- A player’s first column value is the calculated score, the second its entered score (including +’s and -‘s)
- If you don’t set a unique Play ID Board Game Stats will create one for you on import.
- To be able to import, the file must have Unix Linefeeds, and be encoded in UTF-16 little-endian. Text editors like BBEdit or the free TextWrangler can help you with that.
