I build a tool to look more comfortable in savefiles. It´s HTML/Javascript based. At the moment i have only tested this on Firefox Quantum 67.0.4. It has some upload and download functionality to access user filesystem. Download is only via browser download. It has some very basic editor functionality and you can browse a savefile. It has a simple memory function like calculators have.
