The OpenTyper perspective is aimed at MALDI-TOF MS users. Currently it allows to load mass spectras directly and displays a peak list of the selected spectra. Via the save 💾 buttons you can export to different file formats. To recieve a Mass-Up compatible .csv change the delimiter character to , in the CSV MS Converter preferences.
Some file format converters, such as Bruker Flex, filter spectra by default, which you might want to disable under preferences. The profile mass spectrum view can be enabled in the Mass Selective Detector (MSD) settings.
