If you want to use just the pre-built Windows executable, there are no pre-requisites.
Otherwise you will need to install mtgatracker/python-mtga to use the export tool. You can try following forks, if the original python-mtga module fails:
mtga-export reads the MTGA/Unity log file located under:
"%AppData%\LocalLow\Wizards Of The Coast\MTGA\Player.log"
In order for this export tool to work, "Detailed Logs (Plugin Support)" must be enabled in MTGA's Options / Account screen. If the MTGA game developers stop logging to this file, this export tool will not work anymore.
Just download the standalone windows latest pre-built executable from releases.
Export your collection in mtggoldfish format:
mtga-export.exe --goldfish -f mtga_collection_goldfish.csv
Export your collection in deckstats format:
mtga-export.exe --deckstats -f mtga_collection_deckstats.csv
Your collection will be saved to the current folder into mtga_collection_goldfish.csv or mtga_collection_deckstats.csv, which you can use to import into mtggoldfish.com or deckstats.net.
Export your collection in mtggoldfish format:
mtga-export.py --goldfish -f mtga_collection_goldfish.csv
Export your collection in deckstats format:
mtga-export.py --deckstats -f mtga_collection_deckstats.csv
