Golf launch monitors that export a CSV file: FlightScope / FS Golf, TrackMan, Foresight / Bushnell, SkyTrak / SkyTrak+, Uneekor, Garmin Approach R10 / R50, Rapsodo MLM / MLM2PRO and Full Swing KIT. A device that is not listed can usually still be imported by mapping its columns yourself.

Column mapping is most dependable for FlightScope (Mevo, Mevo+, X3) / FS Golf, TrackMan (TM4, iO, Range), Foresight / Bushnell (GCQuad, GC3, Launch Pro) and SkyTrak / SkyTrak+. Uneekor (Eye Mini, Eye XO, Eye XR), Garmin Approach R10 / R50, Rapsodo MLM / MLM2PRO and Full Swing KIT import well too, but give the preview a quick check before you save.
Export the session from your device's own app as a CSV file, then import it. If the app only gives you an Excel spreadsheet, open it and save it as CSV first — the importer reads CSV text.
File import is for golf. Baseball and softball hitting trackers work differently; see tracker data.
